What is an Impulse?
What is for a constant external force, the product of the force
and the time over which it acts on an object
What is the Law of Conservation of Momentum?
What is the total of all objects interacting with one another
remains constant regardless of the nature of the forces between
them
What is a perfectly inelastic collision?
What is a collision in which two objects stick together and move with a common velocity after
colliding
