Newton Born: 4 Jan 1643 in Woolsthorpe, Lincolnshire, England http://www-groups.dcs.st-and.ac.uk/~history/Mathematicians/Newton.html
Isaac Newton came from a family of farmers but never knew his father. He seemed to have shown little promise in academic work.
Newton went to Cambridge for a law degree. There, he began his interest in math and physics.
Newton’s 3 Laws of Motion 1. An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
The first part of the law: A football will remain on a tee until it is kicked off or wind blows it off.
Second part of Law 1: A bike rider will continue moving forward after the bike tire may run into a crack and come to a stop until gravity and the sidewalk stop the rider.
Law 2. The acceleration of an object depends on the mass of the object and the amount of force applied. or F=ma
Acceleration of a 4kg bowling ball will be greater than the acceleration of a 6 kg ball if the same force is applied to both.
3. Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
A runner is able to move forward because of the equal and opposite force the ground exerts on the runner’s foot after each step. = = Force Force
