Gravitational energy examples

Answer 1

every particle want to reduce its potential energy.

so simplest example of this is a wooden piece. When we through it then it will always be going downward to the earth because it want to reduce its potential energy....

Answer 2

• A book held at a height above a table has gravitational potential energy due to its position in the Earth's gravitational field.
• A roller coaster at the top of a hill has gravitational potential energy, which is converted into kinetic energy as the coaster goes down the track.
• The water stored behind a dam has gravitational potential energy, which can be converted into electrical energy using turbines.
