# Newton's Laws

## First Law

An object at rest will stay at rest and an object in motion will stay in motion unless acted on by an outside force.

An example is when a car is driving and hits a wall. The car was in motion but an outside force acted on it. If you were in the car, you would move forward after you hit the wall due to inertia.

Inertia is the tendency of an object to resist a change in motion.

This video represents the first law because the moving car is slowing down because of the cars in the way.

## Second Law

The more force applied to an object, the faster the object will accelerate. Acceleration is the rate in which an object speeds up or slows down.

The equation for Newton's 2nd law is F=MxA. This equation means, force equals mass times acceleration. Mass is the amount of matter in an object.

Force is a push or a pull.

An example of the second law, is if you push a ball with 5 N to the right, and push the same ball with 15 N to the right, the second ball will acceleration will be faster.

## Third Law

For every action, there is an equal, and opposite reaction. An example is when someone jumps on a diving board. The board goes down, but then goes back up.

The video relates to this because the ball goes down, and the ground sends it up.
