Energy Stores and Transfers

Which store of energy is associated with the centre of an atom?

• Kinetic

• Nuclear

• Magnetic

• Elastic

A fast car applies its brakes.

The kinetic energy is transferred to...

• Elastic energy due to the suspension springs being compressed.

• Gravitational potential energy due to the Earth's gravitational pull.

• Thermal energy due to friction between the brakes and the wheel.

• Magnetic energy do to the repulsion between the car and the car in front.
