Motion Vocabulary

TermDefinition
Displacement the length and direction of a straight line between two locations, or positions
Distance a measure of the length of a path that a moving object travels
Velocity a quantity that measures the rate at which the position of an object changes in time. Velocity always describes a distance and a direction
Speed measures the rate at which an object moves along a path. Unlike velocity, speed is not considered to have a direction
Acceleration is a quantity that measures the rate at which an object changes its velocity. People often talk about an object decelerating when the object slows down. An object that slows down is actually experiencing a negative acceleration
force a push or pull on an object
balanced forces When two or more forces act on an object but the object’s velocity does not change
stationary not moving
rest the state of an object being stationary relative to a particular frame of reference or another object
unbalanced forces Forces that cause a change in the motion of an object
Friction the force that resists motion between two surfaces
Inertia the resistance to any change in the state of motion of any physical object. All matter has inertia, and the inertia of matter does not change until the matter is acted on by unbalanced forces that cause a change in motion
Mass the total amount of matter of an object
Gravity the force of attraction that exists between any two or more masses. Gravity can refer to the force that Earth exerts on everything
