Cards Term Newton's First Law Definition An object continues in a state of rest or in a state of motion at a constant speed along a straight line, unless compelled to change that state by a net force. Term Newton's Second Law Definition When a net external force acts on an object of mass M, the acceleration A that results is directly proportional to the net force and has a magnitude that is inversely proportional to the mass. The direction of the acceleration is the same as the direction of the net force. F=MA Term Newton's Third Law Definition Whenever one body exerts a force on a second body, the second body exerts an oppositely directed force of equal magnitude on the first body. Term mass Definition measure of inertia Term weight Definition measure of the gravitational force that the earth exerts on an object. Term normal force Definition the force component that is perpendicular to the surface that an object is in contact with Term equilibrium Definition when an object has zero acceleration. Term net force Definition vector sum of all applied external forces Term inertia Definition the natural tendency of an object to remain at rest or in motion at a constant speed along a straight line. Term friction Definition the force component that is parallel to the surface that an object is in contact with
