What is a difference between newton’s laws of motion and einstein’s theory of relativity? newton’s laws are factual statements, while the theory of relativity is a statement of opinion. newton’s laws can be revised over time, but einstein’s theory of relativity cannot. newton’s laws explain the observations he made, while the theory of relativity was based on one of einstein’s hypotheses. newton’s laws cannot predict what may happen in the future, but einstein’s theory can.
