Higher objects (with further to fall) have greater potential energy. The heaviest of 2 objects at the same height has the greatest gravitational potential energy.

Which object has the most GPE?

Answer: An 8 kg book at a height of 3 m has the most gravitational potential energy. Explanation: Gravitational potential energy is the product of mass of object, height of object and gravitational field.

Which ball has the greatest GPE?

Ball D has the greatest potential energy because it has the greatest height from the ground.
