Question

Daniel is trying to determine if one of Newton’s ideas is a law or a theory. The idea that for every action there is an equal but opposite reaction is a fact, based upon numerous experiments, that has never been revised or changed. The idea is based on observations but is not an explanation of those observations. Daniel should determine that this is a law, because it is a fact that does not change. this is a law, because is based on observations. this is a theory, because it does not explain observations. this is a theory, because it is based on numerous experiments.

Answer 1

This is a law because it is based on observations (Newton's Third Law)
