NEWTON'S LAWS OF MOTION

inertia

This tendency of objects to remain in motion is referred to as ____

inertial frame of reference

An _____ ____ __ ___________ is a perspective considered to identify whether an object is at rest, or is moving with a constant velocity.

first

The _______ law of motion states that “every object continues in its state of rest, or of uniform velocity in a straight line, as long as no net force acts on it.”

equilibrium

For an object to be in _________, either no force must act upon it, or the resultant of the individual forces exerted upon it must have a net force of zero.

Acceleration

_________ is defined simply as a change in velocity

directly proportional

The magnitude of acceleration a is ______ ___________ to the magnitude of the net external force ΣF exerted on an object of a given mass m.

Second

Newton’s _______ Law of Motion states that “if a net external force acts on an object, acceleration occurs—the direction of which is similar to that of the net external force. The net force vector is the product of the body’s inertial mass m and the acceleration vector.”

Third

Newton’s ________ Law of Motion states that if an object A applies a force on object B (FA on B), object B applies a force on object A (FB on A), such that the two forces comprise a respective action and reaction pair. These two forces are of equal magnitude but of opposite direction.
