SUMMARY
The power generated by the falling water at Niagara Falls can be calculated using the formula for gravitational potential energy (PE grav = mgh). Given a mass flow rate of 1.2 x 10^6 kg/s and a height of 50.0 m, the potential energy is calculated as 588,600,000,000 joules. To convert this energy into power, one must recognize that power (in watts) is the rate of energy transfer, specifically joules per second. Thus, the power generated is directly related to the mass flow rate and the height of the fall.
