# Newton's Laws of Motion

### Calvin W. #NewtonsLaws #Kettner

Sir Isaac Newton was born in Woolsthrope, England. When he grew up, he created the modern principals of today's physics. He became an established physicist and mathematician, and was an extraordinary mind during his lifespan. Newton's Principia can be considered the single most important scientific book ever written and published. He lived a long life, and died at the age of eighty-five.

** Newton's first law of motion**, or the law of inertia, states that **on object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an unbalanced force. **In the above picture, the person is moving forward when the car suddenly stopped because of his inertia.

** The second law of motion** states that the **force of an object is equal to its mass times its acceleration. **In the picture above, the force is 100N, the mass is 50kg. Therefore, the dog is pulling the sled at an acceleration of 2m/s squared.

** Newton's third law of motion** states that for** every action there is an equal and opposite reaction. In the picture above, the air comes out of the balloon, forcing the balloon forward. This is the action and its equal and opposite reaction.**
