Newton's Laws of Motion

Front

force

Back

an action exerted on an object that may change the object’s state of rest or motion

Front

acceleration

Back

the rate of change of velocity

Front

inertia

Back

the tendency of an object to resist being moved, or, if the object is moving, to resist a change in speed or direction

Front

equilibrium

Back

the state in which the net force on an object is zero

Front

mass

Back

a measure of the amount of matter in an object

Front

Newton’s First Law of Motion

Back

An object at rest remains at rest, and an object in motion continues in motion with constant velocity (that is, constant speed in a straight line) unless the object experiences a net external force

Front

Newton’s Second Law of Motion

Back

Net force equals mass times acceleration

Front

Newton’s Third Law of Motion

Back

If two objects interact, the magnitude of the force exerted on object 1 by object 2 is equal to the magnitude of the force simultaneously exerted on object 2 by object 1, and these two forces are opposite in direction.
