**Potential Energy = mass x g x height**

'g' represents the 'acceleration of free fall', which on Earth, is always 10m/s²

The proper name for potential energy is gravitational potential energy.

Sometimes, the equation will be written as:

Change in potential energy = mass x g x change in height.

When something is raised from ground level, it has potential energy as it has potential to give off energy of some sort. Eg. a kettle on a table has the potential to give off heat and noise energy.

*E.g, A sheep of mass 47kg is slowly raised through 6.3m. Find the gain in potential energy.*

*Answer: It's even easier than before, you just plug the numbers into the formula. *

*P.E = mgh = 47 x 10 x 6.3 = 2961J *
