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.
