Cards Term Work Definition process of energy transferred in or out of the system, equals the amount of energy transferred, determined by product of force in direction of motion Term Power Definition rate at which work is done or can be done, scalar Term Energy Definition measures ability to do work Term Kinetic energy Definition energy of a moving object or ability to do work Term Gravitational Potential Energy Definition energy that an object has in a gravitational field Term Elastic potential energy Definition energy in a stretched or compressed spring Term Work-energy theorem Definition the net work on a system changes its kinetic energy Term Conservation force Definition force for which works depends on starting and ending points of motion Term Nonconservative force Definition force for which work depends on the path Term Closed (conservative) system Definition system of objects that experience conservation force only Term Open(nonconservate) system Definition system subjected to nonconservative forces Term Mechanical energy Definition sum of kinetic and potential energy Term Conservation of mechanical energy Definition in a closed system total amount of mechanical energy before and after physical process remains the same Term Linear momentum Definition vector physical quantity equal to product of mass times velocity, Term Impulse Definition vector, equal a product of a force with a time interval Term Isolated system Definition group of objects which the net external force (external action) is equal to zero Term Elastic collision Definition collision in the system of 2 or more bodies during which there is conservation of momentum and kinetic energy Term Inelastic collision Definition collision in the system of 2 or more bodies during which there is conservation of momentum but no conservation of kinetic energy Term Jet (rocket) propulsion Definition force produced by an ejected gas on a jet engine’s (a rocket’s) body Term Conservation of linear momentum Definition in isolated system total amount of linear momentum remains the same
