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

∙ 11y agoThe 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.

How does water provides energy?
Water its self does not provide energy, however it can store some of the Suns energy, usefully in the form of potential energy (by virtue of its elevation in the gravity field of the planet).
What is the potential energy of a 8 million kg water falling at 50meters?
Each kilogram of water has 50 joules of gravitational potential energy at the top,and 50 joules of kinetic energy when it hits the bottom.For 8 million of them, that adds up to 400,000,000 joules(in each position).The formula for potential energy is mgh - mass x gravity x height. The above calculation didn't take into consideration the gravity - a factor of about 9.8.
How much gravitational potential energy is released when 1000kg of water descends 200m to the generators?
The formula for potential energy is mass times height times the local acceleration of gravity. Working with this, you have 1000 * 9.8 * 200.
Is a person diving into water an example of potential energy?
Its a bad example, but some potential energy is involved. You convert chemical energy from the fuel to kinetic energy and heat energy. The kinetic energy drives you into the water. There the car sinks because of the height difference and gravity. This is a form of potential energy. A better example would be a person driving up and down a mountain. When driving up a mountain you store kinetic energy into potential energy. On the way down you regain the potential energy you stored, which results in a higher kinetic energy when driving down.
Moving water and falling rocks are an example of what energy?
If the movement is due to gravity, that is the material is moving closer to the earth's centre, then the energy change in the movement is a change in gravitational potential energy. All objects are attracted to the earth by gravity, the force they experience is equal to Mass(kg) x Gravitational Constant G =9.81(meters/sec2), the force being in Newtons. Therefore as energy = force x distance, the potential energy of any object raised through a height H meters is M x G x H, and this will be in Joules.
How is a river potential energy changed into kinetic energy?
As gravity pulls water down a slope, the water's potential energy changes to kinetic energy that can do work.
What alternative energy is reliant on gravity?
Hydropower uses the gravitational potential energy stored in water.
What happens to the potential energy of the water in a river as gravity pulls the water downhill?
Since potential energy is proportional to elevation, the potential energy of water gets less and less as it goes downhill.Its kinetic energy (based on velocity) may well increase, but the question asked about potential energy.
What type of energy has hydro power?
Hydro power has potential gravitational energy. Gravity will move the water. Moving water has kinetic energy.It is also renewable energy.
Can gravity be used to produce electricity?
Yes, gravity is used in hydroelectric schemes when water is run down chutes to drive water turbines which drive electric generators. Hydro depends on the Sun's energy to evaporate water from the ocean and deposit it as rain in the mountains. There is no inherent energy in the gravitational force. The water is lifted up against gravity, gaining potential energy, and then it runs down under the same force to exchange the potential energy for kinetic energy which drives the turbine.
What was the driving force of water?
Generally when water is used as a source of energy it is either the kinetic energy of the flowing water or the potential energy of the water as it changed height that was used as the energy source. In both cases it is gravity that is the ultimate driving force that makes the water move (for kinetic energy) or is the source of the potential energy - which is recovered as the water moves from higher to lower.
What happens when gravity pulls water down a slope?
The water runs down hill. That's why all rivers lead to the sea.
How does tidal energy convert to potential energy?
Potential energy includes that of mass in a gravitational field. The water in a lake high in a mountain has potential energy which can be converted by a hydro electric generator when allowed to fall by gravity. Sea water retained at high tide can be used in the same way when the tide has receded
