since GPE=mgh GPE is gravitational potential energy m is mass g is the gravitational constant, 9.8 h is height drop height and potential energy are directly proportional. as drop height increases, so does potential energy
PE = mg∆h . . . where m = mass, g = acceleration due to gravity, and ∆h = change in height (i.e. drop height) . . . as you can see by the formula, PE is directly proportional to the drop height
