The elevator moved from the 15th floor to the 10th floor at a constant speed. does the PE and KE increase, decrease, or stay constant?

Respuesta :

As the elevator is moved from 15th floor to the 10th floor at a constant speed. It means that the height is decreasing but the speed of the elevator is moved at a constant.

It results that the kinetic stays the same but the potential energy is decreasing.
