Obviously no new energy is created - the Law of Conservation of Energy is still valid. What happens is that potential energy is converted into some other kind of energy, especially heat.

Is a windmill gravitational energy?

no -- the windmill converts the kinetic energy from wind to electrical energy. Gravitational energy is another term for potential energy.


Which two processes can generate energy to help a star maintain its internal thermal pressure?

Nuclear fusion is the primary process in stars that generates energy by fusing lighter elements into heavier ones. Gravitational contraction is another process where a star generates energy by converting gravitational potential energy into thermal energy. Both processes contribute to maintaining the star's internal thermal pressure.


What is gravitational contraction?

Gravitational contraction is the process by which a celestial body, such as a star, shrinks in size due to gravitational forces pulling its material inward. As the body contracts, potential energy is converted into thermal energy, causing the core temperature and pressure to increase, initiating nuclear fusion reactions in stars. This process is essential for maintaining the energy production and stability of stars.


What is an example of gravitational energy into electrical energy?

An example of converting gravitational energy into electrical energy is using a hydroelectric dam. Water stored at a higher elevation has gravitational potential energy, which is converted into kinetic energy as the water flows down through turbines in the dam. This kinetic energy is then used to generate electricity through a generator.


What transfers gravitational potential energy to kinetic to electrical?

A hydroelectric dam converts gravitational potential energy of water stored at a higher elevation into kinetic energy as the water flows down, turning turbines to generate electricity.

Why do we need gravitational energy?

Gravitational potential energy stored in the water reserved in a dam becomes useful to generate electricity.


How is heat related to expansion and contraction?

All energy is transferable. When a body contracts, gravitational potential energy is converted into both kinetic energy and thermal energy. Heat is released by contraction. Conversely, heat is used for expansion.

How did gravitational contraction affect earth?

Gravitational contraction raised the temperature of Earth early in it's formation.


What is the Stellar theory?

The Stellar Theory is a historical scientific theory that suggested stars generate energy through the process of gravitational contraction. Proposed by scientists like Kelvin and Helmholtz in the 19th century, it was later replaced by the theory of nuclear fusion as the primary energy source for stars.

What is a Kelvin-Helmholtz contraction?

Kelvin-Helmholtz contraction is a contraction of a star once it is formed and before it is hot enough to ignite its hydrogen. The contraction converts gravitational potential energy into heat, some of which is radiated, with the remainder used to raise the internal temperature of the star.


How is ATP utilized in the process of muscle contraction?

ATP is used in muscle contraction to provide energy for the movement of muscle fibers. When a muscle contracts, ATP is broken down into ADP and phosphate, releasing energy that powers the movement of the muscle fibers. This energy is needed for the myosin heads to bind to actin filaments and generate the force required for muscle contraction.
