At what point in a reservoir do the water contain the most gravitational potential energy

Where is the most water found on earth (i.e. the largest reservoir)?

Water held behind a dam would best reflectMultiple Choicepotential energy.chemical energy.kinetic energy.mechanical energy.heat energy.

What is an example of gravitational potential energy

A 0.20 kg stone is held 1.3 m above the top edge of a water well and then dropped intoit. The well has a depth of 5.0 m. Relative to the configuration with the stone at the topedge of the well, what is the gravitational potential energy of the stone–Earth system:(a) before the stone is released.(b) when the stone reaches the bottom of the well?(c) What is the change in gravitational potential energy of the system from release toreaching the bottom of the well?

Explain the concept of gravitational potential energy.
