An object in motion (or at rest) will to stay in motion (or at rest) until an outside force acts upon it.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• Newton's 4th Law

Whats Newtons First Law?

• The more force applied to an object the faster it will accelerate.

• An object in motion will stay in motion and an object at rest will stay at rest unless acted by an outside force.

• for every ection there is an equal and oposite reaction
