What is the applications of gravitational potential energy into mechanical energy?

Answer 1

In dams, water is often allowed to fall down onto turbines; here, the mechanical energy is converted into electrical energy.

Answer 2

Gravitational potential energy can be converted into mechanical energy in various applications such as hydroelectric power plants, where the potential energy of water stored at a height is converted into mechanical energy as it falls and turns turbines to generate electricity. Similarly, Roller Coasters use gravitational potential energy to propel the cars downhill, converting it into kinetic energy for a thrilling ride.
