A rock at the edge of a cliff has potential energy. This energy may be converted to kinetic energy by the force of gravity if it falls off the cliff.
kinetic energy
The type of energy of a boulder sitting on a cliff is potential energy. Potential energy is possible energy as opposed to actual energy. If it were to start rolling down the hill, the energy would change to kinetic energy.
If it's not moving it doesn't have any energy
A rock that is sitting on top of a cliff has what is called potential energy.
A rock at the edge of a cliff has potential energy. This energy may be converted to kinetic energy by the force of gravity if it falls off the cliff.
U = potential energy = mass * acceleration due to gravity * height U = 20 kg * 9.81 m/s2 * 100 m U = 19,620 Joules
U = potential energy = mass * acceleration due to gravity * height U = 20 kg * 9.81 m/s2 * 100 m U = 19,620 Joules
By virtue of its position on the top of the cliff it has "potential" energy. If it were to fall off the cliff this potential energy would be converted into "kinetic" energy (the energy in movement of a mass).

The higher rock has more potential energy

Gravitation Potential EnergyA rock sitting on a cliff has this energy as graity is pulling it down but the cliff is keeping it upChemical Potential EnergyWhen your body uses food to create and store energy as fatsElastic potential energyWhen your stretch and elastic around something it has this energy as the stretchyness is kept
