## Newton's First Law

Definition - An object at rest will stay at rest, and object in motion will stay in motion, unless acted upon by a unbalanced force.

My Definition - An object will stay still, an object put into motion by an unbalanced force will stay in motion until stopped by another unbalanced force.

Interia - The ability for an object to resist change

## Newton's first law real life example

Take cars for an example. Your body moves at the speed of the car. When the car stops, and your not wearing a seat belt, it looks like this

(See below)

08b COMUNICATE SAFETY ADAC Crash test Child without seatbelt TECHNICAL

## Newton's first law Real example part 2

When wearing a seat belt, the seat belt is the unbalanced force, forcing you to go the speed of the car when it stops, preventing your body from flying forward as seen in the video above.

## Newton's Second law Definition

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

My definition - The law of acceleration and force.

## Newton's Second law Example

The formula of force is F=ma. The 5 ways an object can accelerate is by velocity - Speed up, slow down, or change direction. Acceleration can be showed/visualized by an arrow.

Which is harder; Pushing an empty shopping cart or a full shopping cart? If you guessed the empty one, you are correct. Since the empty shopping cart has less mass than the full shopping cart, it will be able to accelerate faster, while more force needs to be applied to the full shopping cart to match the empty one's speed/acceleration.

## Newton's Third Law Definition

For every action, there is an equal and opposite reaction.

My definition - When you throw a ball at the wall, the wall will throw it back at your speed.

## Newton's Third Law real life example

When you sit down in a seat, the seat responds to the same amount of force that you are applying to the chair, resulting in it able to support you, or equal forces. If the chair couldn't apply the same amount of force that your sending, you'll either fall through the chair, or break the chair.
