What are action and reaction pairs?

When there is a force being applied, there is simultaneously an equal and opposite force being applied.


Action-reaction pairs stem from Newton's Third Law, which states that all forces come in pairs.

For example, if you push on the wall with a force of 10 N, then the wall will exert a force back on you with a magnitude of 10 N.

It is typically denoted for forces between two objects #a# and #b# as:

#=>F_{"a on b"} = - F_{"b on a"}#
