Isaac Newton

Newton created three laws of motion. The first law states that an object in motion stays in motion unless acted upon by an unbalanced force. It also states that an object at rest stays in rest unless acted upon by an unbalanced force.

Newton's third law states that for every action there is an equal and opposite reacion.

Newton's second law states that the cceleration of an object depends on the objects mass and by how much force is being exerted on to the object. This means if the object has a large mass then more force has to be exerted on to it, to get it in motion. Also if the object has a small mass then a less amount of force will have to be exerted on to it to get it in motion.

Isaac Newton was born on January 4, 1643, and grew up on a farm in Lincolnshire, England. His father passed away three months before he was born. When he was born his mother remarried and left him to live with his grandma. His mother never lived with him again untill her second husband passed away.

Newton invented the first practical reflecting telescope and developed a theory that white light is made up of ROYGBIV (rainbow colors) by shining white light through a prism.

Force is any influence that an object goes through that changes the objects speed, distance, or geometrical construction. Force is measured with the SI unit newtons and in an equation is labled as F.

Friction is the resistive force acting between bodies that oppose each other slowing the object down. For example, a ball rolling on the ground will come slowly come to a stop because of friction. There is friction between the ball and the ground.

Isaac Newton died on March 21, 1727 and was never married. He wrote that one reason he studied science was because it filled his mind with mysteries. It is said that he died from murcury poisoning or by other chemicals he used.

In kenimatics, the speed of an object is the magnitude of its velocity.

Newton studied how his own eyes work by sticking a bodkin between his eyeball and eyesocket. He noted what happened.
