Mason has a small rubber ball. How can he design a test to see how the speed of the ball moving downward affects the energy of the ball?

• Drop the ball and then throw it up in the air and measure how high the ball bounces each time.

• Drop the ball on a hard floor and on a carpet and measure which surface makes the ball bounce higher.

• Drop the ball from the same height several times and measure whether it bounces the same height each time.

• Drop the ball and then throw it down toward the floor and measure how high it bounces each time.
