At what point in a waterfall, do the drops of water contain the most gravitational potential energy?

Answer 1

In a waterfall, the drops of water contain the most gravitational potential energy at the highest point of the waterfall, just before they start to fall downward. This is because potential energy is directly related to an object's height above the ground, so the higher the water is in the waterfall, the greater its potential energy. As the water falls and loses height, it also loses potential energy, which is converted into kinetic energy as it accelerates downwards.
