What is kinetic energy?Show answer
Kinetic energy is the energy an object has because it is moving. The formula is:
What is gravitational potential energy?Show answer
Gravitational potential energy is the energy an object has because it is raised up high. The change in gravitational potential energy when an object is lifted is:
What are energy changing between the two stores?Show answer
When an object falls, gravitational potential energy is transferred to kinetic energy, so it speeds up. When it rises, kinetic energy is transferred to gravitational potential energy, so it slows down.
