A student drops a ball three different times.


The table shows the ball’s kinetic energy upon hitting the ground from different heights.

The student claims that a ball dropped 3.0 meters would have fewer than 96 joules of kinetic energy upon hitting the ground. Is she correct? Why?

She is right! The higher the drop, the less kinetic energy the ball will have upon hitting the ground.

The student is wrong. The higher the drop, the more kinetic energy the ball will have upon hitting the ground. When an object is dropped from a height, its potential energy is converted to kinetic energy as it falls. Therefore, a ball dropped from a height of 3.0 meters would have more kinetic energy as it hits the ground, and if the table indicates that a ball dropped from that height has more than 96 joules of kinetic energy, then the student's claim is incorrect.
