Energy in Sport
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, potential and kinetic energy is described here.
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 a height is said to have potential energy, as if it is released it will gain speed (kinetic energy) while losing potential energy.
