An elevator motor does more work if the elevator moves quickly to the top floor than it does if it moves slowly.

Question

Quizplus · Accepted Answer

The work done by the elevator motor is determined by the force it applies (to counteract gravity) and the distance it moves the elevator, not the speed at which it moves. The amount of work done is the same regardless of how fast the elevator moves, assuming it's lifting the same weight the same distance.
