# Issac Newton

### Boigraphy

born on January 4, 1643, in Woolsthorpe, England, Isaac Newton was an established physicist and mathematician, and is credited as one of the great minds of the 17th century Scientific Revolution. With discoveries in optics, motion and mathematics, Newton developed the principles of modern physics. In 1687, he published his most acclaimed work, Philosophiae, Natrualis, Principia Mathematica (Mathematical Principles of Natural Philosophy), he also discovered that white light is made of many colors.

### Contribution

I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

III. For every action there is an equal and opposite reaction.

### Impact

Isaac Newton's 3 laws of motion are used every day by people. Now that we know how physics works, it has helped us go to space many times and even to the moon.
