In a hydroelectric dam, the gravitational energy of the water is converted into electrical energy as the water falls. Consider just one cubic meter (1000 kg) of water that falls a distance of 500 ft.
Assuming that the energy conversion is 100% efficient, how much electrical energy can be obtained as it falls?
Please express your answer both in joules and in kilowatt-hours.​
