Lecture 7 - Gravitation
... The gravitational force on you is one-half of a third law pair: the Earth exerts a downward force on you, and you exert an upward force on the Earth. When there is such a disparity in masses, the reaction force is undetectable, but for bodies more equal in mass it can be significant. ...
