Question

A rock is pushed out of a six-story window that is 60 feet above the ground. What energy changes occur as the rock falls to the ground?
A)
The potential energy of the rock is destroyed as it falls.


B)
The potential energy of the rock is transformed into kinetic energy.


C)
The kinetic energy of the rock is transformed into potential energy.

Answer 1

Answer:

B) The potential energy of the rock is transformed into kinetic energy.

Step-by-step explanation:

Our understanding of Physics tells you the potential energy due to the rock's position in the gravitational field is transformed into kinetic energy as the rock gains speed (and loses height).
