Newton's Laws of Motion

By: Brooke

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.
