An impulse depends on

• weight and force

• force and time

• electric charge and time

• none of these

If the change of momentum of an object is 50kg m/s, we can say the impulse is equal to:

• 0 N s

• 25 N s

• 50 N s

• 100 N s

The air bag on a car reduces the force experienced by the driver, by extending the time of impact.

• True

• False

Which of the following has the greatest momentum?

• a scurrying cockroach

• a parked semi-truck

• more information is needed

The recoil speed of a rifle is much less than the exit velocity of a bullet because...

• the rifle experiences a smaller force
• the rifle experiences a smaller change in momentum
• the rifle has a much greater mass
• the rifle does not obey the laws of physics
