Newton's Third Law
Students get too focused on THE THREE LAWS instead of just modeling force and motion.
The problem with this law is when it is described in the following way:
Newton's Third Law: For every action, there is an equal and opposite reaction.
Not all textbooks say that, but if you ask a random person on the street that is likely what they will describe as Newton's third law.
The Best Version of Newton's Third Law ————————————–
short version.
Forces come in pairs. Forces are an interaction between two objects. This means that if object A pushes on object B, then object B pushes on A with the same force but in the opposite direction.
Our favorite analogy is with distances. Distances are between two points. The distance from A to B is equal but opposite the distance from B to A. See. It's simple.
