Momentum Basics
This is the formula for momentum
What is p= m × v?
Impulse is calculated by multiplying these two things together
What is force and time?
This law states that total momentum in an isolated system does not change.
What is the Law of Momentum Conservation?
These are the units for momentum
What is kg·m/s?
This is what an impulse causes to happen to an object
What is a change in momentum?
A 3500 kg empty freight car at 5 m/s couples with a stationary 15,500 kg loaded car. This is their combined speed after.
What is approximately 0.92 m/s?
A 70 kg football player runs at 8 m/s. What is his momentum?
What is 560 kg·m/s?
Between a hit-and-stick collision and a rebounding collision, which one produces the larger impulse
What is a rebounding collision?
An astronaut (80 kg) throws a 10 kg oxygen tank at 4 m/s. What is the astronaut's recoil speed.
What is 0.5 m/s (in the opposite direction)?
Unlike speed, momentum has what associated with it?
What is a direction
An 80 kg football player running at 10 m/s must receive an impulse of this amount to be stopped
What is –800 N·s
A 3000 kg truck at 10 m/s hits a parked 1000 kg car, sending it off at 12 m/s. This is the truck's speed after.
What is 6 m/s?
A 1200 kg car has a momentum of 24,000 kg·m/s. What is its velocity
What is 20 m/s
A 1000 kg car hits a wall at 10 m/s and rebounds at 5 m/s. What is the impulse experienced by the car
What is –15,000 N·s?
A 100 kg fullback runs east at 7 m/s and collides with an 80 kg linebacker running west at 8.75 m/s. What is the result?
What is no score (the net momentum is zero)
