Three should be Four

              Isaac Newton had many great accomplishments and yet he only gets three laws. His first law being an object in motion stays in motion in a straight line unless acted upon by a net force. His second law being force equals mass times acceleration. His third law being every force has an equal and opposite force. Those three laws are what he is most recognized for. The problem is he really should have been given a fourth law, the law of gravitation. This law states “every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers” and Newton deserves to be recognized for it. All four of these laws relate not only to astronomy but also to physics and so many other things we see every day. We cannot just leave one out. Without the law of gravitation Newton’s laws are truly incomplete. Why Newton was only given three laws will always be a mystery to me.
