In Newton's third law, do you consider there to be one force or two forces involved? My thinking is that there is only one force which acts equally in magnitude (conservation of momentum) and opposite in direction for each object. However, many sources that I find on the internet claim that there are two forces. Example:

Doesn't the action and reaction refer to the objects and not the force(s)?

These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is:
For every action, there is an equal and opposite reaction.
Doesn't the action and reaction refer to the objects and not the force(s)?
