3. What is the difference between a law about gravity and a theory about gravity?(14 Points) A law says objects fall, while a theory of gravity explains the pull between masses A theory of gravity is less scientific than a law of gravity A theory about gravity is just a guess, while a law is proven forever A law describes what gravity does , while a theory ex- plains why gravity works
