**NEWTON'S THREE LAWS OF MOTION**

**NEWTON'S**

FIRST LAW

OF MOTION

FIRST LAW

OF MOTION

The Law states that:

An object at rest stays at rest and an object in motion stays in motion with the same speed and same direction unless acted upon by an unbalanced force.

Also known as the law of inertia

Inertia

Inertia is a tendency to do nothing or to remain unchanged

Every thing that has mass follows the law of inertia

This picture is an example of inertia because when the wagon hit the brick, inertia made the blocks fly forward. The blocks weren't physically stopped, the wagon was stopped when it hit the wall, the blocks continued in a straight line.

This is an example of inertia because when you flick the card, the coin will fall into the cup and the card will fly out under the coin. this happens because the coin is the object at rest because force was not applied to it when the card was flicked.

**NEWTON'S SECOND LAW OF MOTION**

The law states that:

Acceleration depends on the object's mass and on the net force acting on the object.

Basically, it takes more force to move objects with more mass than it is to move objects with less mass.

F=MxA

Force = Mass x Acceleration

Key Components:

Acceleration,

Mass,

and

Net force

Acceleration:

Increase in the rate or speed of something and the rate of change of velocity over time

Formula for finding acceleration:

Acceleration= net force/mass

Mass:

Quantity of matter in an object

this pencil has mass

but this car has more mass

Unbalanced force:

Stronger force acting on an object. Also known as the resultant force.

Real world application

A car crashing into a wall

Real world application

It would be harder to kick the wall to move it

than it is to kick a ball to move it.

it's because the wall has more mass than the ball.

**NEWTON'S THIRD LAW OF MOTION**

The law states that:

With every action there is an equal and opposite reaction.

Key components:

Action-reaction pairs

Action-Reaction pairs:

Example: A baseball bat hitting a ball. The ball forces the bat to go back and the bat forces the ball to go forward

When one ball swings to the left, it makes the other ball swing to the left then it swings back to the right to hit the other balls.

the pressure stored up in the rocket is released downward which makes the rocket go up.

Real world applications:

when you row a boat you push forwards and the boat is propelled backwards
