SUMMARY
The total gravitational potential energy (Ep) of 3.0 x 1010 kg of water flowing over Niagara Falls, which has a height of 65 m, is calculated using the formula Ep = mgh, resulting in 1.91 x 1013 J. To determine the power represented by this water flow, the relationship power = energy/time is applied, where energy is the gravitational potential energy and time is one hour. This leads to a clear understanding of the energy dynamics involved in the waterfall's flow.
