Newton's Third Law

Newton's Third Law concerns equal and opposite forces. It states that, 'If A exerts a force on B, then B exerts an equal but opposite force on A.'

This video shows how this works in two real life situations involving skateboarders, and rockets.

It is Newton's Third Law that allows rockets to launch into space.

The rocket exerts a force on the gases downwards and so the gases exert a force on the rocket upwards.
