Newton's 1st and 2nd Laws of Motion

What does Newton's First Law of Motion state?

• An object's acceleration is proportional to the amount of force applied, and inversely proportional to the mass of the object.

• An object at rest will remain at rest, while an object in motion will continue to move at a constant velocity, unless a net force acts.

• For every force, there is an equal and opposite reactive force.

• Inertia is a force which acts on all objects.
