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 wrong. The higher the drop, the less kinetic the ball will have upon hitting the ground.

The student's claim that a ball dropped from 3.0 meters would have fewer than 96 joules of kinetic energy upon hitting the ground is incorrect. The correct response is:
She is wrong. The higher the drop, the more kinetic energy the ball will have upon hitting the ground.
As an object falls from a greater height, its potential energy converts to kinetic energy, resulting in greater kinetic energy at the moment of impact.
