The average hitter needs about 50 milliseconds to instinctively assess the speed and location of an incoming pitch. Both papers can be downloaded. You can actually hear where the sweet spot is just by tapping a bat yourself. endobj /V 18 0 R Baseball players were known to carve or whisk their own bats from various hardwoods during the early days of amateur baseball. Movies showing the collision of a baseball with a cricket ball and the collision of two billiard balls are shown in the page on collisions. /V 21 0 R Both the swinging bat and the pitched ball possess kinetic energy, which is generated by the players who swing the bat and throw the ball. Current research on the physics and science behind the game of cricket centers on the performance of the batsmen and bowlers. A similar question: The bumper on a pool table is at a height so that the pool ball does not skid when it hits it. /P 8 0 R For further details, see American Journal of Physics, September 1998 and also American Journal of Physics.

Preliminary In order to indicate the origin of the baseball bats problem, the following preliminary are worth mentioning. That is, a large fraction of the stored elastic energy in the wall is retained as vibrational energy in the bat. You also have the option to opt-out of these cookies. endobj The shoulders reach maximum speed first. It is not easy to find information on the actual rate of spin of a softball in flight, but it is relatively easy to measure, at least at low ball speeds and low spin speeds. A great way to keep a rhythm throughout your swing is to step or stride toward the pitcher. By combining the results of these two separate experiments, we can then work out what happens when a bat is swung at an incoming ball. That should sound like more of a thud, because youre not hearing the vibrations inside the wood. The bat then magnifies that force by a factor of about 100-5,000 lb or so when it collides with the ball, enough to squash the ball in half. Thats the sport that demands the most from the athletes who compete in it. Balls compress along the same F vs x curve, regardless of the ball speed, although the actual compression curve for a given ball will depend on its stiffness. J,g]g+e/h_!_gCtO=0f)$P%cIi8Zdfc5&3j_8$7g. Why dies the bat vibrate inside or outside of the sweet spot? Good eyesight. Their sweet spots are anywhere between 10.16 and 25.4 cm from the barrel end. Baseball is a science that is based on fluid dynamics. To increase the acceleration of the ball while it is still moving, a bat that strikes it harder will most likely accelerate faster. At other impact points, the impact is usually felt as a sting or jarring of the hands and forearm, particularly if the impact occurs at a point well removed from the sweet spot. The second definition is where the ball comes off the bat fastest. An aluminum bat is much lighter than a wooden bat, increasing its range and allowing it to hit the ball farther. In theory, this should mean that a homerun hit right on the sweet spot would sound different from an off-target pop fly. A similar result is obtained when swinging cylindrical rods, as described in a paper that can be downloaded here. The impact of a bat and a ball is still not properly understood. Hitting a ball incorrectly can make a wooden bat break due to the grain of the wood. The majority of hitters take a stride when hitting, which helps the timing of their swing. . Strike at 12 cm Strike at 17 cm Strike at 24 cm Strike at 31 cm. /N 19 0 R All batters knew was that when you made contact about two-thirds of the way down the bat, it felt good in your hands. /WhitePoint [0.9505 1 1.089] A high-end bat is designed for major league hitters in the 31-to-32-ounce (878 to 907 grams) range. The node sweet spot differs from the center of percussion sweet spot. Nathan hopes to test the theory of Robert Adair, a Yale University physics professor and baseball guru, who believes the subjective sweet spot sits on the node where the bat's lowest frequency vibrations drop out. The dead spots in the bat will cause a vibration to be sent down through the handle of the bat into the hands, which ultimately causes vibration or a stinging feeling. Edd Roush holds the distinction of being the heaviest Major League Baseball player in terms of weight. 5 0 obj The relevant collision equations are derived in the Physics of Baseball and Softball book (and elsewhere) and are: 1. But the bat vibrates strongly for impacts near the tip of the bat and near its center of mass. Since F = m*dv/t, we can integrate the force waveform to measure ball speed vs time, then integrate v = dx/dt to measure the shift in the ball CM vs time. >> One of these sweet spots relates to vibration. These vibrations travel in waves up and down the length of the object. Adair provides a few answers in his book The Physics of Baseball but he does not give the directions or the torques. See, the trouble with wood is that it vibrates. The sweet spot of a bat exists because bat vibrations are not excited significantly at that spot. The sweet spot of a bat exists because bat vibrations are not excited significantly at that spot. Players tend to feel a zing in their hands; often called bat sting. 28 0 obj A bat with an end loaded weight indicates that it weighs between 30 and 28 ounces. The tangential COR is defined in the same way as the normal COR, but in terms of the horizontal speed of the ball at the contact point rather than the normal (ie vertical) speed of the contact point. For those of us not trying to make it to the majors, using a wooden bat is mostly just a reminder that hitting a baseball is either painful or frustrating, depending on whether youve made contact with the ball or not. The three elements of a game of baseball are critical, and the game is built around Newtons laws of motion.

The Physics of Baseball. The outgoing speed of the ball is just the sum of the two separate parts - the speed when the bat is at rest plus the speed when the ball is at rest. The sweet spot of a baseball bat Rod Cross Physics Department, University of Sydney, Sydney 2006, Australia Received 10 November 1997; accepted 22 January 1998 The sweet spot of a baseball bat, like that of a tennis racket, can be dened either in terms of a vibration node or a centre of percussion.In order to determine how each of the sweet spots inuences the ''feel'' of the . If you hit . Last . /N 24 0 R Rather, most coaches and others think in terms of wrist torque, which is probably much too small to provide the necessary large couple near the end of the swing The couple must come mainly from the two arms, not the wrists. First and foremost, we develop a simple but effective theoretical model to give a rough estimate for the sweet spot of the bat. Baseball bats have a sweet spot which is the ideal location on the bat to hit the ball for maximum performance. We and our partners use cookies to Store and/or access information on a device. The ball rotated more than 1/4 but less than 1/2 of one revolution from one frame to the next, each frame being 0.04 sec apart. >> In bats made of maple wood, like the Axe Bat, it's easy to find the strongest grain. 1 inch in length is huge. /N 9 0 R A rough estimate would be that the ball rotates 1/4 revolution while it is in the pitchers hand, and while the hand moves forward say the last 0.2 m. If the hand moves forward at 10 m/s = 22.4 mph then it moves 0.2 m in 0.02 sec, so the spin rate would be 12.5 rev/s or 750 rpm. For a fastball, this wake gets pushed down, which then pushes the ball up .. In practice, batters tend to prefer bats that are lighter, rather than more powerful, since lighter bats are easier to swing and make it easier for the batter to connect with the ball. })(); Designed by Elegant Themes | Powered by WordPress, The Ultimate Guide to Baseball-Themed Online Slot Games, How To Hem Baseball Pants: A Step-by-Step Guide For Customizing Your Look. More comparisons can be made by adding more information. The material of the bat can affect its performance, as lighter bats tend to be more responsive and have higher exit velocities. It is almost as easy as walking. This equation for acceleration can , Dry ice is the name for carbon dioxide in its solid state. /ColorSpace [/Indexed /DeviceRGB 255 28 0 R] Scientifically speaking, this is the weakest part of a wooden baseball bat. The second you swing one, there is a certain romance to it. Typical results are shown here for a superball, a baseball and a sorbothane ball. Thick walls are also needed to help prevent the walls dinting or cracking. Since the CM traces out a spiral rather than a circular path, the center of the circle moves, as the bat is swung, along the path traced out by the inner circle of black dots. /N 6 0 R /Length 459 stream Continue with Recommended Cookies, Copyright 2009-2023 real-world-physics-problems.com. You can test your childs grip by having him or her hold the bat straight out in front of them, parallel to the ground, with their dominant hand. What is the fluid speed in a fire hose with a 9.00 cm diameter carrying 80.0 l of water per second? The wood bat is ultimately the best choice for any player who wishes to use a bat with the most natural power and the fastest speed. But opting out of some of these cookies may affect your browsing experience. /V 7 0 R The ball bounces backward spinning counter-clockwise. A baseball bat is typically between 30-34 inches in length and can weigh anywhere from 24-30 ounces. /P 11 0 R The sweet spot's location for maximizing how far the batted ball travels after being hit can be calculated scientifically. What is velocity of bullet in the barrel? The weight and construction of a bat also affects the bounce factor q, and it affects the time and position of the bat at which the swing speed is a maximum. << 2.1. When it comes to bats, one inch in length is equivalent to an ounce of weight. The third law explains what happens to a bat when it strikes a ball. /BitsPerComponent 8 Rather, the physics depends more on the ratio of the bat and ball speeds, regardless of whether the actual speeds are around 1 mph or 100 mph. Its center of mass is 52.6 cm from the knob end. The length, weight, and shape of the bat also affect its performance, as longer bats tend to have more power, and heavier bats tend to have more control. But man, hit it right on the sweet spot and it feels like you are a baseball god. A model is developed for the collision between the baseball and bat, taking into account the transverse bending vibrations of the bat. Thats the sweet spot. The higher the number, the heavier the bat will be, meaning it will have more mass and therefore more power when it makes contact with the ball. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. } The technique here can be be used to measure the performance of any bat, at least at low ball speeds. Each impact was recorded on a video camera at 25 frames/sec. The sweet spots location for maximizing how far the batted ball travels after being hit can be calculated scientifically. When To Know Its Time To Replace Your Baseball Mitt, Customizing Your Baseball Bag: A Guide To Personalizing Your Equipment. The impacts were at distances of 2, 7, 12, 17, 24 and 31 cm from the end of the barrel. This force is required to change a 5 1/8th-ounce ball from a speed of 90 mph to a speed of 110 mph, this distorts the baseball to half its original diameter and the bat is compressed one fiftieth of its size.. The shapes of the force vs time curves are interesting since they tell us how the force on the ball varies with the amount of compression. White ash, sugar maple, true hickory, yellow birch, red oak, and Japanese ash are the six wood types that can be used in bats in Major League Baseball. There is a significant difference between end-load and balanced softball bats in terms of weight distribution. Both papers can be downloaded here and here. The whole mass of the bat is not involved in the collision, unless the collision happens to occur at the centre of mass of the bat. The ball also generates potential energy through the bat, resulting in a powerful, far-reaching hit. R. Cross, Physics of Baseball & Softball, DOI 10.1007/978-1-4419-8113-4 14, c Springer Science+Business . A bat that is too light also hampers the development of a solid, level swing. 1 0 obj /Height 99 All this means that if goal of the bats design is to provide more power and speed, it makes it more likely to to crack and shatter. In this article, well explore the various components that go into making a baseball bat, as well as how they work together to help a hitter put their best foot forward. In file A, the ball spins faster than in file B, both before and after the bounce. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. There is enough physics in it to keep a PhD student busy for a few years, but it could also be done by any high school student as a simple introduction to the physics of baseball. endobj The physics behind this phenomenon involves the transfer of energy from the bat to the ball. So grab your bat and lets dive into the science behind the swing! Baseball players obsession with bats is second nature to them. /P 20 0 R In theory, the ball bounces best for an impact at the center of mass of the bat, provided we can ignore bat vibrations. Some of the numbers change with actual speed, but the physics doesnt change. For example, a 33-inch bat with a -3 rating weighs 30 ounces. This makes the game easier to pick up and more exciting to watch otherwise, every hit would only be a single. Physics 1998 The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. So, using a heavier bat should result in faster hit balls, which means the hit ball will travel farther. /R [52 73 308 791 ] George Jackson is the founder and lead contributor of Physics Network, a popular blog dedicated to exploring the fascinating world of physics. One of the definitions of the "sweet spot" is the location of the node at the barrel end of the bat. It minimizes vibration of the bat and results in the maximum energy delivered to the ball, meaning it travels the farthest. When a batter hits a ball, the bat will rebound from the force of the collision. >> The ratio of ball speeds after and before colliding with the bat is called the is combined with the kinematic properties of the bat (determined from the moment-of-inertia of the bat and the impact location) to obtain the Bat-Ball Coefficient-of-Restitution, or BBCOR for the collosion. These modes are shown in the diagram above. In principle you could also work out the acceleration due to gravity in Sydney, but not very accurately. Though all of this means that us amateurs dont want to have batting practice for more than 10 minutes, it does help you train. The frequency is typically between 1000 Hz and 2500 Hz, meaning that the wall vibrates in and out 1000 to 2500 times in one second. James Sherwood has a similar site http://m-5.eng.uml.edu/umlbrc describing test procedures used to certify baseball bats and balls at the University of Massachusetts Lowell. So, why does the MLB still use wooden bats? Its center of mass is 52.6 cm from the knob end. If a player can maintain the same bat swing speed with a heavier bat, the heavier bat will produce higher batted ball velocity and an increase in distance.

The effect of the hands on the centre of percussion is described in American Journal of Physics, , 622-630 (2004). This cookie is set by GDPR Cookie Consent plugin. Except, of course, when you hit the sweet spot. The ball is 72 mm in diameter. This point, usually 5-7 inches from the barrel end, does not move when the bat is vibrating in its first (or fundamental) bending mode. /R [52 74 308 585 ] Analytical cookies are used to understand how visitors interact with the website. on: function(evt, cb) { And we end up with 12.6 meters per second , Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, to more than 1,200 m/s (3,900 ft/s) in modern rifles with high-velocity cartridges such as the , Summary. Finally, if players started using bats made of a better material, the game would become dangerous as the baseball would start travelling much too fast. Most people find that an impact between the nodes of the first two modes (node1 and node2 in the diagram) feels best since both modes are then excited only weakly. The fundamental mode of a wood bat has a node located typically about 17 cm from each end and a frequency typically of about 170 Hz. Theres a certain romance to wooden baseball bats that goes away the second you swing one. This is not an easy rating to obtain. Not hitting the ball with the sweet spot of the bat causes more vibrations, which causes the sting for the batter. The physics of baseball Baseball players know from experience that there is a ``sweet spot'' on a baseball bat, about 17cm from the end of the barrel, where the shock of impact with the ball, as felt by the hands, is minimized. 18 0 obj /Length 996 When one object collides with another, some of the energy from the impact goes into vibrational waves that travel through each object. The sweet spot (where you want to hit the ball consistently) is located about 2 in from the end of the barrel to about 6-7 in on an adult bat. If you hit the ball on the "sweet spot" of the bat, you get the feeling of a solid connection with the ball. It is critical not only for the sake of performance, but also for the sake of safety. MLB . If the ball is struck at the sweet spot of the bat, then the batter feels almost no effect at all. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. << If you are between the ages of three and nine and weigh less than 60 pounds, you should buy a 28-inch bat if your height is between three and four inches. To squarely hit a fastball, everything has to . { Hit the ball at this spot, and the least amount of vibration will travel throughout the bat. The bat was swung through an angle of about 30 degrees to strike the ball. << Otherwise, the effective mass of the bat is less than its whole mass. /P 8 0 R The second definition is where the ball comes off the bat fastest. >> In general, swing weight increases with actual weight, but swing weight also depends on bat length and weight distribution. Experience. Although most baseball players may not know the deep details, they usually understand that it is not just the skill and effort they put into their swing, but also the specifications of their baseball bat which will impact the success of the hit. Similar results are obtained at much higher ball speeds, the forces and x values being correspondingly much larger. /P 17 0 R These are effectively the same as the vibrations that travel through the air and reach your ear, where you hear them as sounds. A first guess would be at the tip of the bat since the tip travels the fastest. The player has a unique preference for wood bats, which is why it is so important to select one. >> Wood bats hit farther than metal bats, which is the clear distinction between them. /F 3 0 R << These cookies track visitors across websites and collect information to provide customized ads. endobj The result: a harder-hit ball. Elastic behaviour in the vertical direction is described by a number called the coefficient of restitution (COR) which is about 0.5 for a baseball, depending on ball speed. Mass has no effect on distance, but if you cant generate enough bat speed to overcome mass, you are doing yourself no favors and going backwards. the location which produces maximum batted ball speed. Some results for an Easton BK7 aluminum bat are shown below in 13 QuickTime movie files, each about 1 Mb. For further details, see American Journal of Physics, September 1998 and also American Journal of Physics, 69, 231-232 (2001). The physics of the three sweet spots of a baseball bat is discussed and the location of the ball impact point on the bat that leads to maximum ''power'' (greatest batted ball speed) is determined. A right-handed batter has an advantage in a sport where even the best hitters only succeed three times out of ten. Thank you so much for. The batter exerts some 6000-8000 pounds of force on the ball. The sweet spot of a bat exists because bat vibrations are not excited significantly at that spot. Learn how the sweet spot correlates with movement and vibration. There's no stinging, no vibration and no broken bat. A baseball bat is shaped in such a way to have a "sweet spot." The sweet spot is due to the fact that the CP and the VN coincide. This is the online home for all things baseball. This area is a product of physics, as the sweet spot is located at the center of percussion, which is the point on the bat that produces the least amount of vibration when hit. When we say sweet spot we mean about six different things, says Dan Russell, a professor of acoustics at Penn State. If the bat approaches a ball incident at speed vin then. Are heavy bats are more powerful than light bats? dKoL!8Ka#EV,@V!\j8ZFbp6EE<9cn=N6j0nf;(&;QU6bUD')c@\ (7Boo^^S:71(MN]ZQX/+Cbu.lK"p74pe1T%s.DY%&\1TdJhr54.M9au6>79n6`Q:4 The shoulders reach maximum speed first, then the upper arms, then the forearm and finally the bat. The impact point 2 cm from the tip of the Easton bat is a dead spot where the ball doesn't bounce at all, so q = 0. How much force does a baseball bat generate? Second, we give a simplified abstract form of bat which facilitates the description and modeling study. Yes, every ounce makes a difference. /P 4 0 R /P 11 0 R The wall of a bat is relatively heavy and returns only some of its stored elastic energy to the ball, keeping the rest to itself so it can ping as loudly as it wants to. I simply wanted to know whether a hand launched ball spins at around 100 rpm or whether it could be as high as 1000 rpm.

Learn how to add this technique to your swing while still keeping a balanced, relaxed approach to the ball. hitting a baseball is either painful or frustrating. If you hit a baseball somewhere other than the sweet spot, your hands will feel the vibrations. Baseball bats are an integral part of the game of baseball, and their physics is an important aspect of the sport. Elastic behaviour in the horizontal direction can be described by a tangential coefficient of restitution, which is about 0.5 or 0.6 for a superball but only about 0.2 for a baseball on a rigid surface. Hence, there are two vibration nodes in the barrel. From that you can work out the speed and spin of the ball before and after it bounces. >> Softer and less dense varieties of maple that are more likely to break have been banned by Major League Baseball. The flight of a ball through the air depends strongly on how fast it spins, and in what direction it spins. Registration on or use of this site constitutes acceptance of our Terms of Service. This is because physics plays a major role in how the bat interacts with the ball. /R as well as the force at right angles to that, given by M (dV/dt). A good power hitters bat is an end-loaded one, which allows the player to hit the ball farther. Maple bats are the most durable and have a larger sweet spot, making them ideal for power hitters. However. not apply to baseball or softball bats. If you have two bats, each with the same weight the bat that carries more weight in the end will perform better in terms of speed. Its center of mass is 52.6 cm from the knob end. But its not that simple. The lines behind the bat, passing through the axis, mark out angles of 5, 10, 15, 20, 25 and 30 degrees. While the center of mass moves one way (nearly upward here), the handle moves the opposite way (nearly downward). Learn How To Personalize Your Hat With Vinyl Stickers!

Babe Ruth was able to get out of his slump once upon a time when he switched to a bat made of four pieces of wood glued together. Bats in the United States are primarily made of aluminum, which accounts for nearly all of them. /V 22 0 R Share your thoughts with us below! where V = bat speed at impact point just before the impact. The majority of wooden bats are made from ash, with maple, hickory, and bamboo following in their footsteps. The ideal is the 110 turn model. Those two are usually close, but theyre not exactly the same. The various supposed sweet spots effectively add up to a sweet zone, about two inches wide, right on the meat of the bat. /V 24 0 R As a smaller player, you will generally be able to achieve faster bat speeds with a lighter bat. The bat is 84 cm long, and has a mass of 849 gram. A recoil of the bat occurs when a ball collides with the bat, causing it to push back against it with equal force. We also offer a variety of resources for baseball players, including tips on hitting, pitching, and fielding. endobj 21 0 obj On average, the sweet spot occurs between 5 and 7 in (12.7 and 17.8 cm) from the barrel end of the bat. It is not difficult to swing a bat. We use the idea that if a body collides with something, then its angular momentum is conserved with respect to the point of impact. However, it will also feel heavier when swung. The tubes were suspended by a length of string so that they could vibrate for a long time without damping. Ball exit speed = q*vin where vin = incident ball speed. Where on the bat is the ball struck with the greatest speed? /V 12 0 R Only a small fraction of that huge force gets back to the handle to trouble the batter. The spot is close to the centre of percussion (COP) for a freely supported bat, so it was thought at one time that the sweet spot might be associated with the COP. The COR for a collision between the bat and the ball is less than 0.59 when energy is lost to vibrations, but can be greater than 0.59 if the bat has a trampoline effect on the ball. How is this described in Mechanics? Understanding the sizes of bats is critical to making the best choice for your game and the best bat for you. As discussed earlier, missing the sweet spot can cause vibrations in the bat. It is almost as easy as walking. /V 3 0 R It is not the actual weight that determines the swing speed but the swing weight (ie the moment of inertia). % >> External forces are the only way to redirect the ball according to the first law of motion. The hand moves forward faster than this in practice, so the spin rate could easily be around 1500 rpm. ** A new article on knuckleballs was added in May 2013 **. If the vibration frequency is less than about 1000 Hz, the end result is that ball comes off the bat at a lower speed than off a wood bat of the same weight and swing weight. There is a difference between a bat and a racquet here, in that tennis strings are very light and give back to the ball 95% of their stored elastic energy. By understanding the physics of baseball bats, players can maximize their performance on the field. 10 0 obj A simple introduction to the physics of the collision problem is given here. In case that didnt quite clear it up for you, lets break this down a bit. A homerun hit right at the sweet spot would sound different than one hit off the target. My particular research interests are two-fold: the physics of the baseball-bat collision and the flight of the baseball.
