Cards in this set: Term Force Definition The medium by which energy does work Term Matter Definition A physical body or substance that occupies space and can be perceived by one or more sense Term Work Definition A transfer of energy from one system to another Term Energy Definition The capacity of a physical system to do work Term Contact Definition Two or more bodies of matter that are sufficiently close together that weak force interactions cause them to deform or accelerate Term Sliding Friction Definition Force of rotation acting on bodies in contact to resist sliding between the bodies Term Static Friction Definition The force of static friction resists movement Term Maximum Static Friction Definition At impending motion, the force of static friction reaches its maximum value Term Kinetic Friction Definition Once motion starts the force of friction is reduced to a constant kinetic friction Term Moment Definition Measure of the tendency of force to cause a body to rotate about a point/axis Term Moment Arm Definition The perpendicular distance from the line of action of a force to a point or axis of rotation Term Magnitude of a Moment (Torque) Definition The product of the magnitude of a linear force tending to cause rotation about its moment arm Term Centre of Mass Definition Point about which all of the bodies points of mass are equally distributed in space Term Center of Gravity Definition The point about which the torques created by the weight of each part of the body are balanced Term Radius of Gyration Definition The effective distance of the mass of a body from its center of rotation
