law of conservation of energy
Energy never disappears
The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.
The total energy in a closed system remains constant.
A swinging pendulum converts kinetic energy to potential energy and back; the energy changes form but the total persists.
This principle underlies all of physics.
