3 LAWS OF NEWTON Bairma Nadtsalova

SIR ISAAC NEWTON Sir Isaac Newton was one of the greatest scientists and mathematicians that ever lived. He was born in England on December 25, He was born the same year that Galileo died. He lived for 85 years. Isaac Newton was raised by his grandmother. He attended Free Grammar School and then went on to Trinity College Cambridge. Newton worked his way through college. While at college he became interested in math, physics, and astronomy. Newton received both a bachelors and masters degree.

While Newton was in college he was writing his ideas in a journal. Newton had new ideas about motion, which he called his three laws of motion. He also had ideas about gravity, the diffraction of light, and forces. Newton's ideas were so good that Queen Anne knighted him in His accomplishments laid the foundations for modern science and revolutionized the world. Sir Isaac Newton died in 1727.

NEWTON'S FIRST LAW Every body continues its state of rest or of uniform motion in a straight line, unless compelled by some external force to act otherwise.

NEWTON'S SECOND LAW The vector sum of the external 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.

NEWTON'S 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
