Grade 7, Newtons Laws of Motion

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
