Cards Term Force Definition The cause of an acceleration, or the change in an object's velocity. Term Contact Force Definition Force that arises from the physical contact of two objects. Term Field Force Definition Force that can exist between objects, even in the absence of physical contact between the objects. Term Force Diagram Definition A diagram of the objects involved in a situation and the forces exerted on ther objects. Term Inertia Definition The tendency of an object to maintain its state of motion. Term Net External Force Definition The total force resulting from a combination of external forces on an object; sometimes called the resultant force. Term Equilibrium Definition The state in which there is no change in a body's motion. Term Action-Reaction Pair Definition A pair of simultaneous equal but opposite forces resulting from the interaction of two objects. Term Weight Definition The magnitude of the force of gravity acting on an object. Term Normal Force Definition A force exerted by one object on another in a direction perpendicular to the surface or contact. Term Static Friction Definition The resistive force that opposes the relative motion of two contacting surfaces that are at rest with respect to one another. Term Kinetic Friction Definition The resistive force that oposes the relative motion of two contacting surfaces that are moving past one another. Term Coefficent Friction Definition The ratio of the force of friction to the normal force acting between two objects.
