Energy

Conservation of energy

In a closed system, energy cannot be gained or lost. In most sporting situations, although it will seem like energy is lost or gained, what you will find is that the energy changes from one type to another. There are several types of energy

Kinetic energy

Kinetic energy is the energy of motion, as described by the following formula.

kinetic energy = 1/2 mass x velocity^2

Potential energy

For example, an object that is moved to aheight is said to have potential energy, as if it is release it will gain speed (kinetic energy) while losing potential energy.
