GPE

When something goes higher in the air, the GPE increases. When something goes lower to the ground, the GPE decreases.

• Work done (for GPE) depends on how high it was lifted and how much it weighed
• Gravitational Potential Energy Store Change=weight x height change
• Gravitational Potential Energy Store Objects change=mass x gravitational field strength x height change

1. The moon has a field strength a lot lower than us, which means the pull on an object is lower. Because of this, humans can lift things really heavy on the Moon compared to Earth.
