Newton's 1st law- If an object that is not moving will not move until a net force acts upon it, and if an object that is in motion will not change velocity (accelerate) until a net force acts upon it.
Newton's 2nd law- the rate of change of momentum of a body is proportional to the resultant force acting on the body and is in the same direction.
Newton's 3rd law- to every action there is always opposed an equal reaction

1st- a car. The car does not move until you make it move and doesnt stop until u make it stop.
2nd- an ice skater- Pushing on the ice
3rd- rocket ship. The rocket going up is the action and the reaction is the flame

Just think of it like this:
Newton's 1st Law : Inertia
Newton's 2nd Law : F = ma
Newton's 3rd law : Action- reaction

For Newton's 3rd Law, and example is when you fire a gun. The kickback from the gun is the opposite reaction. You have to place the butt of the gun against your shoulder and sometimes it leaves a bruise because of the force of it slamming back into your shoulder when you fire.

I have an example for the First Law (The Law of Inertia).
I don't move unless someone really motivates me!
