How Does height affect the bounce of a ball?
A ball hitting the ground with greater speed should bounce higher than a ball striking the ground with less speed; therefore, a ball dropped from a greater height will bounce higher than a ball dropped from a lesser height. When a ball is bouncing high into the air, it will continue to bounce for some time.
How high does a golf ball bounce when dropped?
When dropped from any height onto a hard surface, their ball will rebound 0.8 (80%) of the original height, whereas the competitors ball will have a rebound ratio of only 0.7 (70%).
Why do the bounce height of this ball decrease?
Since the height to which the ball will bounce is directly proportional to its energy (barring effects of air friction), with a coefficient of restitution of less than one the ball will bounce less and less high.
How do you calculate ball bounce?
200 represents the initial height, and (2, 111) represents the second height after the first bounce at 111 cm. We now know that this ball has a 55.5% rebound ratio. We can fill in a table or calculate the height of the ball after each further bounce….Student Exploration.
| 1 | 200 |
|---|---|
| 2 | 111 |
| 3 | 61.605 |
| 4 | 34.190775 |
| 5 | 18.97588013 |
Why does height affect bounce efficiency?
The higher the bounce, the more efficient the ball is. Balls which do not bounce high are less efficient as they have lost energy. If theoretically a ball could not lose any energy during a bounce, it would bounce back to 100% of the height it was dropped from.
What is the relationship between drop height and bounce height?
The relationship between drop height and bounce height is only linear for small drop heights. Once a ball reaches a certain height, the bounce height will begin to level off because the ball will reach its terminal velocity.
How high should a golf ball bounce?
The ball should be dropped from a height of 12 inches, so a second person should measure the height of the golf ball (from the bottom of the fall to the ground) BEFORE the first person drops it.
Why doesn’t a ball bounce back to its original height?
Did you find that a single ball never bounced back to the height at which you released it, regardless of the ball you used? During a collision, some of the ball’s energy is converted into heat. As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height.
How Does height affect bounce efficiency?
The efficiency of a ball can be calculated by dropping and measuring the height of the bounce. The higher the bounce, the more efficient the ball is. Balls which do not bounce high are less efficient as they have lost energy.
How do you measure ball bounce height?
Quadratic Model: Height of Single Bounce Using a formula from physics that relates an object’s height to the length of time it has been falling, h = 16t 2 (16 is half the rate of acceleration due to gravity in feet per second squared), it can be determined how long it takes to fall from each height.
What is a bounce height?
A: The height to which a ball will bounce depends on the height from which it is dropped, what the ball is made out of (and if it is inflated, what the pressure is), and what the surface it bounces from is made out of. A ball’s gravitational potential energy is proportional to its height.
Why don t the balls bounce back to their original heights?
The reason it doesn’t bounce higher than where it started is simple: some of the ball’s energy is lost as heat when it bounces, so it doesn’t have as much going up as it did coming down. Knowing that, you might figure that a ball could never bounce higher than the height from which is was dropped.
Why does a golf ball bounce on a flexible surface?
BOUNCE OFF A FLEXIBLE SURFACE This is a pretty picture of a golf ball and an 8mm thickslice of a large superball sitting on a slab of polished granite. The ballspins faster when it bounces off the superball slice since the tangentialcoefficient of restitution is much larger. A golf ball that spins faster willtravel further.
How is the bounce of a ball related to physics?
The ballgrips the table during each bounce and reverses both its direction of motionand the spin direction. There is a lot of interesting physics in both of theseevents. A fundamental physics problem inball sports is to measure or calculate the way the ball bounces.
What is the ratio of vertical speed before and after a bounce?
The ratio of the vertical speed after the bounce to that before thebounce is called the COR (Coefficient of Restitution). We can also define ahorizontal COR in an analogous way, in terms of the horizontal speed of thecontact point at the bottom of the ball.
What happens when the ball bounces on the right side of the table?
The ball retraces its incident path when it bounces on the right hand side of the table. The ball grips the table during each bounce and reverses both its direction of motion and the spin direction. There is a lot of interesting physics in both of these events.
