Newton's Three Laws

First Law:

This law states that every object in motion will stay in motion unless an outside force interferes.
Example: If a small child is playing with a toy car and slides it across the floor, it will keep rolling until it hits a surface, such as a counter.

Second Law:

This law is based on inertia.An important equation involved with this law is F=ma. This law states that the change in velocity or acceleration is directly proportional to the magnitude of the force and inversely proportional to the mass of the object.

Third Law:

This law states that for every action has an equal and opposite reaction. For example, if a person pushes against a wall, the wall is pushing against the person as well.
