Newton’s 3 Laws Law 1 An object in motion stays in motion unless a force acts on it. An object at rest stays at rest unless a force acts on it. Law 1 Example It was moving day at the Burton house. Little Susie Burton couldn’t lift her box of toys so she was dragging them down the stairs. They got away from her and tumbled to the bottom where they crashed on the floor. This shows law 1 because the box started falling down the stairs because of the force of gravity, not by itself. It did not stop until it hit the bottom and the floor stopped it. Law 2 The more mass an object has the harder it is to start it moving or change its direction. Once it is moving it is harder to stop it, the more mass it has. Law 2 Example The Burtons had a pool table. Little Billy Burton tried to move it but he couldn’t. This is Law 2 because it took more force to move the pool table because it was heavy and they had a hard time stopping because it was heavy. Grandma, Grandpa, Mom, Dad, Uncle Don, Uncle Bill, and Aunt Donna all had to help. They got it going, but then ran into a wall because once they got going they could not stop! Law 3 For every action there is an equal and opposite reaction. (for every up there is a down, for every push there is a pull, for every forward there is a backward.) Law 3 As the Burton family got ready to take off to their new home Mrs. Burton set her soda can on the back bumper of the truck. She forgot it was there and got in. Mr. Burton hit the gas and the truck hit the road. The forgotten soda can flew off the back of the truck and landed on the street. This is Law 3 because the truck went forward and the can went backward. They were equal and opposite actions.
