Why does a ball bounce higher from 75 centimeters?
The balls dropped from 75 centimeters will bounce higher than thosedropped from 50 centimeters, and the balls in the 50 centimeter trials will bouncehigher than those in the25 centimeter trials. This is because the higher the starting height of the ball, the higher the ball’s potential energy. An object has potential energy because of its position.
How do you measure the bounce of a basketball?
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.
