What is gravitational energy?
Q: What is gravitational energy?
A: Gravitational energy is the potential energy held by an object because of its high position compared to a lower position.
Q: What is gravitational potential energy?
A: Gravitational potential energy is mechanical energy minus kinetic energy associated with gravity or gravitational force.
Q: How is the quantity of gravitational potential energy measured?
A: The quantity of gravitational potential energy is measured in Joules (J), a scalar quantity.
Q: From where does an object get gravitational potential energy?
A: An object gets gravitational potential energy when it moves uphill.
Q: How can gravitational potential energy be turned back into kinetic energy?
A: When the object comes back down again, the gravitational potential energy is turned back into kinetic energy, i.e., movement.
Q: How does gravitational potential energy help us in cycling?
A: Gravitational potential energy helps us in cycling by keeping us powered when we are coming back down from riding uphill.
Q: How does gravitational potential energy help keep planets in orbit around the Sun?
A: Gravitational potential energy helps keep planets in orbit around the Sun by maintaining the gravitational force pulling them towards it.
