Newton's laws have been disproved. Go up against Einstein instead. He (Newton, and a friend at the same time) did invent calculus though, and he knew why his laws would get disproved, just didn't see it. Einstein's theory of relativity both proves and disproves Newtons laws of motion. It is suggested that it is hard, but it really isn't. Special Relativity's a cake walk (the one that both proves and disproves Newtonian Physics) General Relativity and what follows is a bit harder.

The Three laws are the three lies.
