1. The problem statement, all variables and given/known data If the forces in Newton's third law are equal and opposite, they cancel, and thus nothing can ever accelerate, so the law is absurd. 2. Relevant equations Argue why this isn't true. This is from my textbook, a very strong argument. 3. The attempt at a solution Hey I'm in intro-physics, so my knowledge is very limited. But I would argue that if an object was moving at constant velocity, and impacted a wall with equal opposing force, then object would stop accelerating immediately. If this law is absurd, then we would not be able to identify the counter force coming from the wall. Thus, we would conclude the object just stops moving. anyone got a great argument? Please feel free to add/correct anything.
