    As a rock falls without air resistance, which of the following is true? (Points : 1) The kinetic energy of the rock transforms into potential energy. All the potential energy becomes kinetic energy at the instant it is dropped. Part of the potential energy of the rock becomes kinetic energy during each part of the fall. The potential energy of the rock has been transformed into thermal energy by the time the rock reaches the ground.

    Can you tell when is potential energy more? when the height of the rock is from the ground is higher or lower?
