1. Momentum p = m v Momentum = mass * velocity momentum is directly proportional to an object's mass momentum is directly proportional to the object's velocity

2. units for momentum Momentum = mass * velocity Units = km m / s

3. Momentum is a vector quantity. vector quantity = quantity which is fully described by both magnitude and direction. fully describe the momentum of a 4-kg lab cart rolling eastward at 2 m/s.

4. Sample problem 6A page 209 A 2250 kg truck has a velocity of 25 m/s to the east. What is the momentum of the truck? Given: m = v = Find: p = Equation: p = mv Work problems 1 - 3 page 209
