GPE meaning
Energy stored in an object due to its height in a gravitational field
GPE formula
GPE = mass × gravitational field strength × height
Symbol formula
GPE = m × g × h
GPE units
Joules (J)
Mass units
Kilograms (kg)
Gravitational field strength units
N/kg
Height units
Metres (m)
Earth’s gravitational field strength
Approximately 10 N/kg
Increasing GPE
Increase mass or height
Decreasing GPE
Lower the object or reduce mass
Energy transfer when lifted
Chemical store → gravitational potential store
Energy transfer when falling
GPE → kinetic energy
If no air resistance
GPE lost = KE gained
Work done link
Work done lifting = increase in GPE
GPE depends on
Mass, height, and gravitational field strength
Zero GPE reference
Usually ground level
Key idea
Higher objects have more gravitational potential energy
