The three laws of motion explain how an object will either stay in motion or what makes it move,Force= mass X acceleration, and action and reaction. This essay will basically take the dry basics of the rules and elaborate and give examples of how they work so you will have a better understanding of the laws. Including examples of labs that demonstrate, lets introduce the first law. Newton’s 1st law of motion states that an object at rest will stay at rest until acted on by larger force. Objects in motion will stay in motion until stopped by a larger force. Basically this is stating that an object will not move if it isn’t affected by an unbalanced force. It also says that if it starts to move, it will continue moving in that direction until a larger force stops this. Say you put a basketball in a swivel chair and start to roll the chair. If you stopped the chair, the ball would continue in the same direction until you, another object, or friction stops it. When it is at a constant speed it is a balanced force just like it was before it started moving. If you put a restraint on the ball, like tying it to the chair, it would stop it from continuing to go. This is the reason we have seat belts in cars, so we don’t fly through the windshield if you stop quickly, because without that restraint, you’d continue to go right out of the car. And depending on how much you weigh, and how quickly the car stopped, you would probably go pretty far. This is an example of Newton’s 2nd law of motion. Newton’s 2nd law states that the smaller the object is, the more acceleration is there will be. The larger the object, the less acceleration there will be. This is because Force= mass X acceleration. Basically the more mass you have and the more force you have, the more you will accelerate. So say you have three different sized balls. They all had different masses and you role all
