An object with momentum is hard to stop Momentum • Momentum = Mass x Velocity p = m x v
CHECK FOR UNDERSTANDING • Which has more momentum, a race car or an 18 wheeler if both are traveling at 65 mph? Explain your answer. Solution the truck it has more mass
CHECK FOR UNDERSTANDING • Can an object moving slowly have a large momentum? Explain your answer.
CHECK FOR UNDERSTANDING • Can an object with a small mass have a large momentum? Explain your answer.
CHECK FOR UNDERSTANDING • Can an object at rest have a large momentum? Explain your answer.
No An object at rest has no momentum, no matter how large its mass. Momentum = Mass x velocity = Mass x (0) = 0
CHECK FOR UNDERSTANDING In 1974 Nolyn Ryan’s pitch was clocked at 45.05 m/s (100.08 mi/hr). A standard base ball has a mass of 0.145 kg. What was the momentum of the ball? • p = mv • P = (45.05 m/s)(0.145 kg) = 6.532 kg.m/s
