I lift a 20kg ball up 2.5 meters off the ground on Earth.
-Earth’s gravitational acceleration is about 9.8 m/s2.
a) How much gravitational potential energy does the ball have at this point?
b) How much work did I do lifting up the ball?
c) If I lift the same ball the same distance on the Moon, then how much gravitational potential energy will it have? (Moon’s Gravity = 1.6 m/s/s)
