# Why is Isaac Newton Famous?

Issac Newton is famous because he discovered the Universal Law of Gravitation. His study looked a little like this: ‘If the force of gravity reaches the top of the highest tree, might it not reach even further particularly might it not even reach all the way to the obrit of the Moon!, The orbit of the moon about the Earth could be a consequence of the gravitational force, because the acceleration due to gravity could change the velocity of the Moon in such a way it followed an orbit around the Earth. He also invented the three laws of motion: 1. Every object in a state of uniform motion tends to remain in that state of motion unless an external forces is applied to it. 2. The relationship between an object’s mass, its acceleration, and the applied force.(F=ma). In this law the direction of force vector is the same as the direction of the acceleration vector. 3. For every action there is an equal and opposite reaction. In his ‘spare time’ he also invented the reflecting telescope, and invented calculus. For more information see here:
