**Newtons Three Laws of Motion**

Law 1

The law of inertia states that, “An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.”

If not affected by an unbalanced force an object is able to continue moving forever

Law 2

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

Law 3

Have you ever wondered how a rocket ever finds the great power it needs to go into space?

Law 2

F=Ma

Law 1

Inertia

Law 3

For Every Action

There is an Equal and Opposite Reaction

The ramp is very smooth and neglects the idea of friction, therefore the ball will continue the way it is unless stopped by an unbalanced force.

Inertia is the act or tendency to resist a change in motion.

Basically heavier objects require more force to move the same distance as lighter objects.

According to Newton, an object will only accelerate if there is a net or unbalanced force acting upon it. The presence of an unbalanced force will accelerate an object - changing its speed, its direction, or both its speed and direction.

It is the Third Law of Motion which states that for every action, there is an equal and opposite reaction.

According to Newton, whenever objects A and B interact with each other, they exert forces upon each other.

First, what is a force?

A force is a push, pull or twist upon an object that results from its interaction with another object.

F = MA
