P2.3.2 Gravitational Potential Energy 0.0 / 5 ? PhysicsWork, Energy and MomentumGCSEAQA Created by: MaddiCreated on: 24-04-14 21:57 What does the gravitational potential energy of an object depend on? The gravitational potential of an object depends on its weight and how far it moves vertically. 1 of 7 What happens to the gravitational potential energy of an object when it moves up or down? The gravitational potential energy of an object increases when the object goes up and decreases when the object goes down. 2 of 7 How can we calculate the change of gravitational potential energy of an object when it moves up or down? The change of gravitational potential energy of an object is equal to its mass x the gravitational field strength (10N/kg) x its change in height. 3 of 7 What are the units? GPE: J. m: kg. g:N/kg h:m 4 of 7 What is power? Power is the rate of transfer of energy. 5 of 7 How can you calculate power? Power = E / t 6 of 7 What are the units? P: W. E: J. t:s 7 of 7
