Newton’s First Law: Inertia
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
Newton’s Second Law: Force
The acceleration of an object depends on the mass of the object and the amount of force applied.
Newton’s Third Law: Action & Reaction
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
