Energy an object possesses because of its position in a gravitational field
Kinetic energy
Energy from motion

Before the egg fell, it possessed gravitational potential energy and no kinetic energy. At the end of the drop, the egg and rubber band system now possess less gravitational potential energy, no kinetic energy (it is not moving) and a lot of elastic potential energy due to the stretched rubber bands. This illustrates the Law of Conservation of Energy. Most of the initial gravitational potential energy transferred to elastic potential energy at the bottom of its fall. Some energy also went to heat energy.
