Slide8FORMULA
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.

Slide22Slide23Point A: Potential Energy is the highest. (2000 J)
Kinetic Energy = 0 velocity = 0
TME= 2000 J mass=
h= 8m
Point B: PE = J Kinetic Energy = 1000 J velocity=TME= J mass = h= 4 m
Point C: PE = J Kinetic Energy = 2000 J velocity=TME= J mass = h= 0 m
Point D: PE = J
Kinetic Energy = J velocity
=
TME= J mass =
h= 2 m
