Momentum Vocab

Momentum Vocabulary

Physical system A system of 2 or more objects in which momentum is conserved during interactions of the objects.
Momentum A vector quantity defined as the product of an object's mass and velocity.
Impulse The product of the force and the time over which it acts on an object. Also change in momentum.
Collision An event in which 2 or more bodies come together.
Elastic Collision A collision in which the total momentum and total kinetic energy remain constant.
Inelastic Collision A collision in which the total kinetic energy of the colliding particles is not the same after the collision as before it.
Perfectly inelastic collision A collision in which two objects stick together and move with a common velocity after colliding.
Law of Conservation of Momentum The total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects.
