The gravitational potential energy store of an object increases when
it moves up
The gravitational potential energy store of an object decreases when
it moves down
The gravitational potential energy store of an object increases when it is lifted up because
work is done on it to overcome the gravitational force
the gravitational field strength at the surface of the moon is
less than on the earth
the change in the gpe of an object is
Eₚ = m (mass) x g (gravitational field strength) x h (change of height)
