Final answer:
The statement is false because kinetic energy decreases as a rock is thrown up and turns into potential energy, which then reconverts to kinetic energy as it falls.
Step-by-step explanation:
The statement is false. When a rock is thrown into the air, its kinetic energy is converted into potential energy as it rises. The kinetic energy decreases with height as the rock slows down, and at its highest point, the kinetic energy is at its minimum while potential energy is at its maximum. Conversely, as the rock falls back down to the ground, its potential energy is converted back into kinetic energy, increasing its velocity and hence, the kinetic energy, but decreasing its potential energy.
