Gravitational Potential Energy (GPE) is the energy stored in an object due to its position in a gravitational field. The formula is:
PE = m × g × h
Where:
- PE is the gravitational potential energy (in Joules)
- m is the mass of the object (in kilograms)
- g is the acceleration due to gravity (in m/s²)
- h is the height of the object above a reference point (in meters)
For example, a 3 kg mass at a height of 5 meters on Earth (g = 9.81 m/s²) has:
PE = 3 kg × 9.81 m/s² × 5 m = 147.15 J
