Isaac Newton was born on 4 January 1643 in Woolsthorpe, Lincolnshire. He died on 31 March 1727 and was buried in Westminster Abbey.
He was 19 when he began his scientific at Cambridge University in England an his interests there were mathematics, optics, physics and astronomy. He received his bachelor of arts in 1665, and was named a fellow of the College two years later.
While in the farm in 1666, Newton saw an apple fall to the ground, and he began to ponder the force that was responsible for the action. While this story has often been considered to be the stuff of legends, Newton confirmed that it did indeed happen.
He first surmised that the apple fell because all matter attracts other matter. He then further theorized that the rate of the apple's fall was directly proportional to the attractive force which the arth exerted upon it. In addition, he suggested the inverse square law. All this were was later know as “Newtons Laws”.
There exists a set of inertial reference frames relative to which all particles with no net force acting on them will move without change in their velocity. This law is often simplified as "A body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force." Newton's first law is often referred to as the law of inertia.
Observed from an inertial reference frame, the net force on a particle is equal to the time rate of change of its linear momentum: F = d(mv)/dt. When mass is constant, this law is often stated as, "Force equals mass times acceleration (F = ma): the net force on an object is equal to the mass of the object multiplied by its acceleration."
Whenever a particle A exerts a force on another particle B, B simultaneously exerts a force on A with the same magnitude in the opposite direction. The strong form of the law further postulates that these two forces act along the same line. This law is often simplified into the sentence, "To every action there is an equal and opposite reaction."
First Law- Pulling a tablecloth from the tabletop while all dishes are still in tact to the table surface.
Third Law- Pushing against the table while sitting on your chair, and you move back behind.
