Isaac Newton

Sir Isaac Newton was born on January 4th 1643. He was a lot of things. English physicist, mathematician, astronomer, and a philosopher. He was the one that came up with Newton's three laws of motion. His first law states that an object at rest tends to stay at rest, an object in motion tends to stay in motion unless acted upon by an external force. The second law states that an applied force on an object equals the rate of change in its momentum. Newton's third law states that for every action there is a equal reaction. It is also said that an apple fell from a tree and dropped on his head. That's what made him formulate his theory of gravitational force.
