Potential and Kinetic Energy

An apple hanging from the branch of a tree falls down.  How does its energy change as it falls?

• The kinetic energy of the apple converts to potential energy.
• The potential energy of the apple coverts to kinetic energy.
• The kinetic energy of the apple remains constant.
• The potential energy of the apple remains constant.
