Gravitational potential energy depends on an object’a mass it’s height above the ground and the acceleration due to gravity. It can be calculated with the equation: Gravitational potential energy (GPE) = mass x gravity x height GPR = mug has Consider the girl on the sled, pictured in the figure above. She has a mass of 25kg and the top of the hill is 4 meters higher than the bottom of the hill. Gravity on earth is 9.8m/s/s. As she sits at the top of the hill, the child’s gravitational potential energy is: GPE = mass x gravity x height GOE = (25kg) x (9,8 m/s/s x (4 m) GPE = 980 SOLVE FOR PE!!
