Back

Kinetic energy (energy of motion) and potential energy (stored energy).

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state.

Front

How does energy transfer occur?

Back

Energy transfer occurs when energy moves from one object to another.

Front

What happens to energy when you throw a ball?

Back

The energy from your arm transfers to the ball, giving it kinetic energy.

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only change forms.

Front

What is an example of potential energy?

Back

A rock at the top of a hill has potential energy due to its height.

Front

What happens to the energy of a rock when it falls?

Back

The potential energy converts to kinetic energy as it falls.

Front

What is an example of kinetic energy?

Back

A moving car has kinetic energy because it is in motion.
