Newton's Laws of Motion
Newton's First Law of Motion
A real life example of this law is passengers in a car. If you are driving and wearing your seatbelt, you accelerate and decelerate with the car. So, if you car hits a wall inertia would want you to fly out, but your seatbelt stops you. When the car hits the wall and its motion stops and you were not wearing a seatbelt, you would keep accelerating forward because there is nothing to stop you from the inertia.
Newton's Second Law of Motion
A real life example of this law can be moving an object. Let's say that you are pushing a 10 pound box and a 1 pound box with the same force. The acceleration will be different because one box is lighter and the force is not as strong on it. So, the difference in acceleration depends on the difference in the masses.
Newton's Third Law of Motion
A real life example of this law is when you sit in a chair. Your body goes downward and land on the chair. The chair creates a force upward. If the chair didn't create this force, the chair would collapse.
Mass - the amount of matter in an object
Force - a push or pull
Acceleration - an increase in the rate or speed of something
