Potential Kinetic Energy

A student creates a ramp by stacking four blocks and then leaning a meter stick against it. She releases four different balls from the same position on the ramp and calculates their speeds. Based on the information in the table below, which ball would you predict to have the LEAST kinetic energy when it reaches the end of the ramp?

• Golf

• Tennis

• Baseball

• Softball
