Meaning
A force pair is the two forces that occur when two objects interact.
About Force Pairs
- The two forces in a force pair may be referred to as an action force and a reaction force.
- When an object "A" exerts a force on object "B" then object "B" will exert a force on object "A". These are a force pair which will be equal in magnitude and opposite in direction to one another.
Examples
 |
| This diagram shows a force pair. It does not matter which is labelled "Action Force" and which is labelled "Reaction Force" |
 |
 |
| This diagram shows the weight as the "Action Force" and the normal contact force as the "Reaction Force". | This diagram shows a rocket with a force pair where each force is equal in magnitude but opposite in direction. |
