Issac Newton Born December 25, 1642 In Woolsthrope a city in Lincolnshire, England Educated at Trinity College Founded the laws of motion and universal gravitation Also founded Calculus

Galileo’s Influences Galileo was an astronomer Achieved the invention of the telescope Stated the first laws of nature are mathematical Newton wanted to clarify Galileo’s main points on gravity and force and friction.

Newton’s First Law of Motion 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.inertial reference framesforcevelocity

Example

Newton’s Second Law 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."linear momentum

Example

Newton’s Third and Final Law 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." In the given interpretation mass, acceleration, momentum, and (most importantly) force are assumed to be externally defined quantities. This is the most common, but not the only interpretation: one can consider the laws to be a definition of these quantities.
