How does gravity change water potential energy?

Answer 1

Take for example a dam, and the process which electricity is produced from water by gravitational force. When water rushes down the penstock into the turbine, it creates a rotational energy. The rotational energy is transfered to the spindle. At which point the spindle passes its energy off to an alternator. The alternator will create electricity. Thus, when you take gravity into account, water is a great potential energy. You need little to no fossil fuels to sometimes create more energy than a power plant. Simple and sweet too, I might have missed a couple key concepts

Answer 2

The potential energy of water increases as it changes from a liquid to a solid, and decreases as it changes from a liquid to a gas. Conversely, the kinetic energy of water decreases as it changes from a liquid to a solid, and increases as it changes from a liquid to a gas.

Answer 3

Gravity acts as a force that can increase or decrease the potential energy of water depending on its direction. When water moves in the direction of gravity, its potential energy decreases as kinetic energy increases. When water moves against gravity, such as in the upward flow of a plant, its potential energy increases as work is done to move against the force of gravity.

Answer 4

As gravity pulls water down a slope, the water's potential energy changes to kinetic energy that can do work. I hope this helped :D
