(In technical terms it is called an ’inelastic collision’.) Let’s jump back into our own shoes on the ground and conclude our observations. Drop a ball from 4 feet. Example 2: i. Department of Physics and Astronomy. A very non-bouncy ball, say a lump of clay, will bounce better on some soft surface like a … I will briefly describe what it is: The machine is configured to serve the ball at a fixed speed to the center of the left (or right) service court; Based on the rotation in 3 directions (X,Y,Z) of the ball, the machine would let the ball land in various positions in the left service court. I have an idea of making a tennis serving machine. Consider the basketball to have an elastic collision with the floor.
Welcome back. Drop the ball from 10 different drop heights, using the video camera to record the bounce heights. Regents Physics Lab #12: Bouncing tennis ball Objective: The purpose of this lab is to collect data about the bounce height a tennis ball reaches, and to use that data to make a prediction. This means that the tennis ball will bounce up and away from the basketball at the same velocity as during the impact (roughly 20 mph). If you look at the ball's speed as a vector, the vertical component of the top-spun ball's velocity is greater than the normal served ball. Equipment: Each group will need a tennis ball and a meter stick. This is the popping sound we hear when the ball is hit. iii. Trial Procedure: 1. When dropped separately, the tennis ball bounces to a height of 0.5m and the basketball to a height of 0.8. Why? Drop the ball through the photogate. ... A tennis ball… Drop the tennis ball from rest from the starting height (H) 2. After its 22nd bounce, it’s bouncing back up less than one millionth of a foot. This will bend the trajectory downwards. Having less energy, the ball doesn’t bounce as high.
ii. Part of a Super Ball’s uniqueness is its ability to bounce in all directions equally. Tennis Physics: Anatomy of a Serve. Toggle navigation ... with the tennis ball on top). Golf balls have a much higher coefficient of resolution because under their plastic skin resides a small, slightly harder, Super Ball. The tennis ball has a mass of 75g and the basketball has a mass of 1kg. LeeH That answer works well for a nice bouncy tennis ball. by Dr. Aaron Titus. After the 32nd bounce, it's bouncing back up by less than one billionth of a foot.
If each time it bounces back up halfway, by the time the ball bounces just 12 times, it’s already bouncing back up less than one thousandth of a foot. Now as we collide with the tennis ball, energy is once again conserved. Whether it’s the motion of the ball in the air, the force on the ball by the racquet, or the bounce of the ball, the laws of physics govern the entire game. ... it must travel within a very narrow range of angles to both clear the net and bounce inside the service box. A photogate near the floor, at a height just above the diameter of the ball, to measure the ball’s speed. So by applying top spin on the ball the way tennis players do, the ball is rotating in the direction of the trajectory. When it hits the ball, the kinetic energy becomes three different types of energy. With the U.S. Open Finals coming up this weekend, the physics of tennis is on display for all to see. A tennis ball and basketball are dropped from a height of 1m (the tennis ball on top of the basketball). The speed of the ball immediately before and immediately after it bounces. Analysis of Double Ball Drop The two slightly separated balls dropped from the same height are seen by a ground observer to approach the surface with velocity v. A ground observer sees the larger ball hit and bounce up with velocity v while the smaller one still approaches. The first type is sound energy. This kinetic energy carries the racquet towards the ball. The tennis ball will bounce higher than the original point of release! Under those rules a tennis ball dropped from 100 inches can bounce no higher than 58 inches, just more than half.
