Isaac Newton was born on December 25, 1643 and was born in Woolsthorpe, near Grantham in Lincolnshire, England. He went to Cambridge University in 1661 and became interested in math, physics, and astronomy. Newton received a bachelors and masters degree. (online) What he is most famous for is developing his three laws of motion. The first law is that an object in motion tends to stay in motion with the same speed going in the same direction unless acted upon by an unbalanced force. An object at rest tends to stay at rest unless acted on by an unbalanced force. His second law states that acceleration is produced when a force acts on mass. The greater the amount of mass is the more force is needed to accelerate the object. His third law states that every action has an equal and opposite reaction (online). There are many everyday examples, and more complex explanations of each of these laws.

Isaac Newton’s first law, an object in motion tends to stay in motion with the same speed going in the same direction unless acted upon by an unbalanced force. An object at rest tends to stay at rest unless acted on by an unbalanced force, is also known as “the law of inertia.” Galileo Galilei developed the concept of inertia years before Isaac Newton was born. “The law of inertia” states that every moving object possesses inertia which keeps it moving unless an external force acts upon it. Basically this law means that all objects naturally want to stay in motion. Objects avoid change in their state of motion unless an outside force causes it (Encyclopedia of Earth and Physical Sciences, 2009)

The second law of motion developed by Isaac Newton states that acceleration is produced when a force acts on mass.” The greater the amount of mass, the more force needed to accelerate the object.” (online). This law is often represented by the mathematical equation, F=ma (force equals mass times acceleration). This means that an object with more mass takes more force to move the...
