Laws of motion

Optics

• In 1672, Newton discovered that when white light passed through a prism it broke up in to a wide color band (rainbow) called a spectrum.
• Next he passed a single through the prism and it remained unchanged.
• From this experiment he concluded that white light is a mixture of colors.
• He also invented
• Newton published the book, Opticks in 1702 which explains the nature of light.

First law: When viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.

Second law:The vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a of the object: F = ma.

Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.

Career

• In 1669, he returns to Cambridge and is appointed professor of mathematics, during his time there he made several discoveries that changed the way we view the world today.
• His book Philosophiæ Naturalis Principia Mathematica was published in 1687 which gained him international fame.
• From 1689 to 1702 he was a member of Parliament in England
