Physics C11:Momentum

Physics C11:Momentum Coach Leach

TermDefinition
Momentum Newton’s “quantity of motion” characteristic of any moving system, directly proportional to both the system’s mass and its velocity
Impulse The change in momentum due to the application of a force
Recoil The reaction force of a projectile on the device that launched it
Conservation of momentum The total momentum of a system, including a multipart system, is conserved if the net external force acting on the system is zero.
Thrust The impulsive force on a rocket- or jet-propelled vehicle accompanying the expulsion of propellant exhaust that accelerates the vehicle
Elastic collision A collision in which kinetic energy is conserved
Partially elastic collision A collision in which the colliding objects exchange some of their kinetic energy for other forms of energy but do not stick together
Inelastic collision A collision in which kinetic energy is not conserved; Some or all of the initial total kinetic energy is consumed in deforming the colliding objects.
Ballistic pendulum An inertial device used to measure the energy of ballistic projectiles
Center of mass The point within a system where the entire mass of the system can be assumed to be concentrated when one is evaluating the behavior of the system according to Newton’s laws of motion; also called the center of gravity
Angular momentum The momentum of a rotating system that is dependent on the angular velocity and mass distribution of the system
