... When two large objects exert gravitational forces on each other, the force on the near side is larger than the force on the far side, because the near side is closer to the other object. This difference in gravitational force across an object due to its size is called a tidal force. ...

Forces & Newton’s Laws of Motion
... force exerted on object 1 by object 2 is equal to the magnitude of force simultaneously exerted on object 2 by object 1. In other words, for every action, there is an equal and opposite reaction. These are called Action-Reaction Pairs. Forces will always come in pairs. Remember that action-rea ...
