The Potential Energy Associated with Gravity Can Be Expressed as PE

question 39

Essay

The potential energy associated with gravity can be expressed as PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.On Earth, the acceleration due to gravity is 9.8 m/s².Calculate the potential energy of a 5.45 kg bowling ball that is sitting 1.0 m above the ground on Earth.If the potential energy of the bowling ball 1.0 m above the surface of the moon is 8.7 kg m²/s², what is the gravitational acceleration on the moon?
