**__Introduction__**
While Newton was in college he was writing his ideas in a journal. Newton had new ideas about motion, which he called his three laws of motion. Newton's first law of motion is usually referred to as the law of inertia. Newton's second law has to do with the relationship between force, mass, and acceleration. And Newton's final law shows how the reaction resembles the previous action.

__**First Law of Motion**__
Newton's first law of motion is sometimes referred to as the law of inertia. It is basically saying that if something is moved or a force is acted on a stationary object, it will move unless another force is acting on it in the opposite direction. Ex: A ball rolling down a hill and then it hits a wall and stops. It stops because there was an opposite force acting on it. A car stopped at a red light is at rest because there is no force making the car move. pushing a marble across a hardwood floor will stay in motion because nothing is acting on it in the opposite direction. media type="file" key="Movie on 2010-11-22 at 12.19.mov" width="300" height="300" In this video, exhibit A (Chris), when he is not in motion, no force is acting on him and his cute little cart. But when he was pushed, a force was now acting on him and his cart. To stop exhibit A, exhibit B (Skillin) pushed in the other direction, making the forces equal to each other, which ending up making exhibit A come to rest. Acceleration is produced when a force acts on a mass. The greater the mass the greater the amount of force needed. This law gives you an equation for the relationship between forces, acceleration, and mass: F=MA. So, if something with a small mass hits an object at rest, it wont go as far as if something with a larger mass, if it hit the same object. Ex: Passing a soccer ball compared to shooting a soccer ball. Shooting the ball will have more force acting on it making the ball go further and faster. If you try to move a large person with your finger, they will not move because there is not enough force to move the great mass. An 18-wheeler hitting a parked car compared to a golf cart hitting the same car. The 18 wheeler will push the parked car futher because it has much more mass.

The man pulling him doesn't need as much force to move the wagon itself because it doesn't contain the amount of mass that the fat kid do

__**Third Law of Motion**__
For every action, there is an equal and opposite re-action. So when a force acts on an object at rest, there is an opposite force acting on the same object, but in the opposite direction. Ex: Punching a wall results in the wall hitting you back. Thats why you feel pain if you hit the wall hard enough because it hits back. Slapping someone's hand means the other hand is slapping yours because there is another force acting back. Hitting a car with another one means you the other car hit yours.

In this video, by pulling the steel ball back and letting it hit the others, it goes through each of them, but since the last ball doesn't have another ball to transfer the kinetic energy to, it absorbs all the energy, making it go in the direction all the other balls were intended to go. Since the ball is attached to the string, it makes it come back, making it equal the force in the other direction.
