Definition
An attractive force between any two objects that depends on the mases of the objects and the distance between them.
Increases as the mass of either object increases, or as the objects move closer.

Term
| Newton's third law of motion |
|
Definition
When one object exerts a force on a second object, the second one exerts a force on the first that is equal in strength and opposite in direction.
To every action force there is an equal and opposite reaction force. |
