Newton's Third Law of Motion

Question

Why is Newton's third law of motion actually considered a law of motion? In my opinion it has nothing to do with motion and more with the nature of forces.

Answer 1

Third law: "For every action there is an equal and opposite reaction."

I wouldn't say it has "nothing" to do with motion.

This law is the reason oars move boats.... feet move skateboards, and jet engines move airplanes.

Answer 2

True Newton's laws are about how force causes motion. The first says: no force no change in velocity, the second tells exactly you how force causes acceleration (i.e. change in velocity) and the third tells you about the reaction to an applied force.
