== =__Isaac Newton’s Life__=

Isaac Newton was born on December 25 (1642-1727). The same year that Galileo died. He was a mathematician and a physicist, and had one of the most scientific intellects. He was born at Wools Thorpe near Grantham in Lincoln shine, where he went to school, but he entered Cambridge University in 1661. He was elected a fellow of Trinity College in 1667. Newton became a professor for the trinity club. In his first lecture course in January 1670. He concluded that during the two plague gears that white light is not a simple entity. Every scientist had believed that white light was a basic single entity, but the chromatic aberration in a telescope lenses, convinced Isaac otherwise. He passed a thin beam of sunlight through a glass prism. Isaac said a spectrum of colors was formed. He argued that white light was a mixture of many types of rays which are refracted at many different angles, and each different type of ray becomes a different spectral color.

=__Newton____’s laws__=

Isaac Newton used three laws to explain the way objects move. The First Law is that an object that is not being pushed or pulled by some force will stay still, or will keep moving in the same line at a steady speed. He said "It is easy to understand that a bike will not move unless something pushes or pulls it".

The Second Law is how force acts on an object. An object accerlates in the direction the force is moving it. For example: If someone gets on a bike ,and pushes the bike forward the bike will begin to move, and if someone pushes it form behind the bike will speed up.

//**A=** f// / //**m**//
 * //F//** = //m// * //**a**//

-Lastly, the Third Law is that if an object is pushed or pulled, it will push or pull equally in the opposite direction. Newton discovered this when he saw an apple fall. He thought and understood that gravity was a attraction between two objects ,and that with more mass the greater the force. This means that the mass of the earth is large that it pulls objects down, towards it.
