 elastic collision a collision in which colliding objects rebound without lasting deformation or the generation of heat impulse the product of the force acting on an object and the time during which it acts impulse-momentum relationship Impulse is equal to the change in the momentum of the object that the impulse acts on. In symbol notation: Ft=∆mν inelastic collision a collision in which the colliding objects become distorted, generate heat, and possibly stick together law of conservation of momentum When no external net force acts on an object or a system of objects, no change of momentum takes place. Hence, the momentum before an event involving only internal forces is equal to the momentum after the event: mv(before event) = mv(after event) momentum the product of the mass of an object and its velocity conservation of energy Energy cannot be created or destroyed; it may be transformed from one form into another, but the total amount of energy never changes. In an ideal machine, where no energy is transformed into heat, (work)input = (work)output and (Fd)input = (Fd)output kinetic energy energy of motion, described by the relationship: kinetic energy = ½mv² machine a device for multiplying forces or simply changing the direction of forces potential energy the stored energy that a body possesses because of its position power the time rate of work: power = work/time watt the unit of power (1 joule per second) work the product of the force and the distance thought which the force moves: W = Fd work-energy theorem The work done on an object is equal to the enegy gained by the object: Work = ∆E
