Gravitational energy is the energy held by an object because of its high position compared to a lower position. I.e. A pencil being held above a table has a higher gravitational potential than a pencil sitting on the table. Gravitional potential energy is Mechanical energy minus Kinetic Energy. It has a scalar quantity measured in Joules (J).
The mathematical formula for the gravitational potential energy of an object is:
Force of gravity =
- m is the mass of the object,
- g the gravitional pull
- h the height above a chosen point.
Typical measurement units for the equation are:
- The value m is in kilograms,
- The value h is in metres,
- The value g is 9.81 metres per second squared.
