A student fires a toy rocket into the sky. When does the rocket have

the most potential energy?
when the rocket has the most fuel
when the rocket reaches its greatest velocity
when the rocket reaches its highest point
when the rocket hits the ground

Answer 1

The rocket has the most potential energy when it reaches its highest point in the sky. At this point, the rocket has converted most of its initial kinetic energy into potential energy due to its increased height and gravitational potential.
