A) What is momentum? What conditions must be satisfied for momentum to be conserved in a system?
B) Describe a situation in which the momentum and kinetic energy of a system is conserved. Are these types of situations typical in common applications?
C) How are Newton's three laws of motion related to the conservation of momentum?
D) Consider a head-on collision between two billiard balls. One is initially at rest and the other moves toward it. Sketch a position vs. time graph for each ball, starting with time before the collision and ending a short time afterwards.
E) As you have drawn the graph, is momentum conserved in this collision? Is kinetic energy conserved?
I would appreciate the answers using a computer (not handwritten), with a clear format, and easily and clearly understandable.
