Impulse and Momentum

The momentum of an object depends upon the object's ___________&_____________.

• size and shape

• mass and speed

• mass and veloctiy

• mass and energy

Cart A is pulled with a 2 Newton force for 2 seconds, and Cart B is pulled with a 1 Newton force for 3 seconds.  Which cart experiences the greatest impulse?

• Cart B
• Cart A
• they are the same

The impulse-momentum theorem states that

• the impulse on an object is equal to the change in momentum it causes 
• the force on a moving object is equal to the magnitude of the impulse.
• the impulse on an object is greater than the change in momentum it causes 
• the impulse on an object is less than the change in momentum it causes

When the speed of an object is doubled, its momentum

• remains unchanged in accord with the conservation of momentum.
• doubles
• quadruples
• decreases

Which takes more force  to catch, a bowling ball or a ping pong ball?

• bowling ball because it has more momentum
• ping pong ball because it has more momentum
• both require the same amount of force when catching
• bowling ball because it has less momentum

An object with a mass of 2000 kg at rest has what momentum?

• 2000 kg m/sec
• 0 kg m/sec
• 2000 kg
• 2000 m/sec
