There is a gravitational force of attraction between the Earth and the moon, but is it mutual? That is, are the forces on the Earth and the moon equal? Most people would say no, the Earth exerts a greater force of attraction because it is larger and has more mass. This is a situation in which Newton's Third Law is relevant. Newton&'s Third Law says that for every force, there is an equal and opposite reaction force. So the force the Earth exerts on the moon must be exactly equal and opposite the force the moon exerts on the Earth.

Fantastic video to demolish misconceptions about Newton's 3rd law! Very clear and with powerful questions that make learners really think about the science described. I added this great video to the @tesScience twitter stream and newsletter. Thanks for sharing.
