237490212	Force	An action exerted on an object that may change the object's state of rest or motion
237490213	Inertia	The tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or directon
237490214	Net Force	A single force whose external effects on a rigid body are the same as the effects of several actual forces acting on the body
237490215	Equilibrium	The state in which the net force on an object is zero
237490216	Weight	A measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe
237490217	Normal Force	A force the acts on a surface in a direction perpendicular to the surface
237490218	Static Friction	The force that resists the initiation of sliding motion between two surfaces that are in contact and at rest
237490219	Kinetic Friction	The force that opposes the movement of two surfaces that are in contact and are sliding over each other
237490220	Coefficient of Friction	The ratio of the magnitude of the force of friction between two objects in contact to the magnitude of the normal force with which the objects press against each other
237490221	Work	The product of the component of a force along the direction of displacement and the magnitude of the displacement
237490222	Kinetic Energy	the energy an object is due to the object's motion
237490223	Work-kinetic energy theorem	the net work done by all the forces acting on an object is equal to the change in the object's kinetic energy
237490224	Potential Energy	The energy associated with an object because of the position, shape, or condition of the object
237490225	Gravitational Potential Energy	The potential energy stored in the gravitational fields of interacting bodies
237490226	Elastic Potential Energy	The energy available for use when a deformed elastic object returns to its original configuration
237490227	Spring Constant	A parameter that is a measure of a spring's resistance to being compressed or stretched
237490228	Mechanical Energy	the sum of kinetic energy and all forms of potential energy
237490229	Power	A quanity that measures the rate at which work is done or energy is transformed
237490230	Newton's Third Law	For every action there is an equal and opposite reaction.
237490231	Newton's Second Law	Force=Mass x Acceleration
237490232	Newton's First Law	An Object at rest will stay at rest; An object in motion will stay in motion unless acted on by an outside force
