• True

• False

A good way to remember the energy stores is

• GTECKMEN

• GTEKMAN

• GTECMEN

• JTECKMEN

What is the principle of conservation of energy?

• Energy cannot be created or destroyed; it can only be transferred.

• Energy can be created but not destroyed.

• Energy cannot be created, but it can be destroyed.

• Energy can be created and destroyed; it can also be transferred.

Which one is not an energy store?

• Gravitational potential

• Kinetic

• Light

A pendulum is never able to swing back to its drop-height. Why?

• Some of the energy is dissipated to the surroundings by heating.

• Some of the energy is destroyed.

• Some of the energy is transferred to nuclear energy store.

Energy is transferred from one store to another by a pathway. Select all the pathways.

• By force

• By heating

• By light

• By sound
