1687- Isaac Newton creates the law of universal gravitation
Every object in the universe attracts every other object. The degree of attraction would depend on the mass of the objects and the distance between them.
1687- Isaac Newton creates the laws of motion
1st law: An object will not change its motion unless a force acts on it. 2nd law: The force on an object is equal to its mass times its acceleration3rd law: For every action force, there is a reaction force equal in strength and opposite in direction
Newton's theory about gravity helped to explain the movement of the planets and the Sun
