Newtons First Law Of Motion: Inertia

Definition:An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This law is often called "the law of inertia".

My Definition: An object in motion will stay in motion until a force is applied to change its motion. And an object not in motion with stay not in motion until a force is applied to make it go in motion.

The picture shows that when your body is in motion once you put another force to it it will suddenly have to stop because of a force applied

Demonstration: A pencil in class is rolling and a force is applied from a chair and makes the pencil stop moving.  

Newtons Second Law Of Motion

Definition: Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

My Definition: when a mass that is bigger is applied to a force that is smaller it cause that force to accelerate to the object.

This shows a small mass is pushing a larger mass and the car isn't moving because it has a heavier mass.

Demonstration: throwing a heavy weight and then throwing a crayon.  

Newtons Third Law Of Motion

Definition: For every action there is an equal and opposite re-action.

My Definition: when an object hits and object if the mass is greater it will make the smaller object go farther.
