gravitational energy
Stored falling power
Gravitational energy is the potential energy an object possesses due to its position in a gravitational field.
The higher something is lifted against gravity, the more gravitational energy it stores—energy that converts to motion when the object falls.
The roller coaster gains gravitational energy as it climbs the first hill.
Hydroelectric dams harness gravitational energy by channeling falling water through turbines.
