# Newton's Laws of Motion

## Newton's First Law of Motion

First Law: An object in motion will stay in motion and an object at rest will stay at rest unless acted on by an outside force. This means that when a force is applied the object will slow down or stop but when force is not applied an object will role on for forever.

## Newton's Second Law of Motion

Second Law: The second law states that the acceleration of an objet is depended upon two variables- the net force acting upon the object and the mass of the object. This means that when an acceleration is applied the acceleration depends on the mass of the object.

## Newton's Third Law of Motion

Third Law: For every force there is an equal and opposite force. This means that when there is a push or pull applied the object being pushed or pull is going in the opposite direction.

## Example of Newton's First Law

When a hockey puck is hit on the ice it will eventually stop because of friction or someone will hit is and it will stop.

## Example of Newton's Second Law

If you use the same force to push a truck or a car, the car will have more acceleration then the truck, because the car has less mass.

## Example of Newton's Third Law

When the air rushes out of a balloon the opposite reaction is that the balloon flies up.

## Equation For Newton's Second Law

Equation: Force = mass x acceleration (F=ma)

The equation above means that to find force you do mass x acceleration

The picture below is showing that if you multiply the force and acceleration you will get the force you are applying.

## Vocabulary For Newton's Laws

Force: A push or a pull

Acceleration: To increase speed

Mass: The amount of matter in an object.

Inertia: The tendency of all objects to resist a change in motion.
