Observations and results Did you find that a single ball never bounced back to the height at which you released it, regardless of the ball you used?
As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height. Had you given the ball an initial push, you would have added energy, and the ball might have bounced back higher.
A well-inflated ball bounces better because it has more air inside. This allows it to push back faster, reducing the contact time and contact area in a collision and thus reducing the heat produced.
Tennis balls also have air inside but they cannot be reinflated. Did you also see how a lighter ball shoots high into the air when released at the same time on top of a heavier ball? Both balls fall at the same speed but the heavier ball gains more energy during the fall. When the lighter ball bounces on the heavy ball they exchange energy, and the lighter ball flies off with some of the energy of a heavier ball.
It reaches way higher than from the height it was released. The heavy ball, on the other hand, is left behind with little energy and does not move much.

Materials A basketball or other large bouncing ball A tennis ball or other bouncing ball that is smaller and lighter than the bigger ball A ping-pong ball, smaller and lighter than both other balls optional A hard surface to bounce balls, preferably outdoors, surrounded by a large open area where a ball can fly without colliding with people or objects A helper optional Camera that films video optional Yard stick that measures meters optional Preparation Gather your test balls in the open area where you will perform the activity.
Note: If your ball does not bounce well, it might be deflated or old. You can add air to some balls like basketballs, soccer balls, volleyballs, etcetera. A bicycle pump with a special piece to inflate balls can help you do the job. Other balls, such as tennis balls or baseballs, wear out with use. Why do you think a deflated ball does not bounce well? Why would a well-used tennis ball not bounce as well? A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor.
The more energy absorbed by the surface, the less that remains in the ball for it to bounce. This is why you should have seen that when you bounced the basketball on a relatively hard surface it bounced higher it lost less energy compared with when it was bounced on a softer surface where it lost more energy.
For example, depending on the type of basketball and surface, you may have seen the ball bounce about 15 inches high on carpet and about 25 inches high on concrete.

Materials At least two different surfaces to bounce a basketball on, with at least one hard surface and one soft surface For example, you could use carpet, concrete, grass, linoleum and a basketball court. The surface needs to be flat and next to a wall or other large perpendicular surface. Tape measure or yardstick Painter's tape or masking tape Basketball A helper Video camera and access to a computer or a large screen on which to watch your recorded video optional Preparation Prepare the walls or other vertical surfaces next to the floor types you want to test so that you can estimate the height of the basketball's bounce.
To do this use a tape measure or yardstick along with the painter's or masking tape to mark every eight inches, starting from where the wall meets the floor and going up to 40 inches high on the wall.
You should end up with five tape marks on each wall. If you are using a video camera, ask your volunteer to set it up so that all of the marked wall measurements as well as the floor are in view. Exponential decay occurs when a population declines at a consistent rate. The corresponding series can be written as the sum of the two infinite geometric series: one series that represents the distance the ball travels when falling and one series that represents the distance the ball travels when bouncing back up.
You can use sigma notation to represent an infinite series. The infinity symbol that placed above the sigma notation indicates that the series is infinite. To find the sum of the above infinite geometric series, first check if the sum exists by using the value of r. Here, when the ball is dropped, it bounces back to two third of the height it is dropped from and then goes back.
So, in other words it covers two third of its height or 96 ft 2 times i. If a is positive and b is greater than 1 , then it is exponential growth. If a is positive and b is less than 1 but greater than 0 , then it is exponential decay. An asymptote is a value that a function will get infinitely close to, but never quite reach.
