Momentum and Impulse Review Activity

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

• size and shape

• mass and speed

• mass and veloctiy

• mass and energy

What happens when a system winds up being isolated?

• The total momentum stays the same during collisions, etc.

• The total momentum drops down to zero.

• All objects will leave the system.

• All energy turns to kinetic 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

After collision, the two objects move off with different velocity. What type of collision is this?

• Inelastic

• Elastic

A 0.250 kg cart moving at 0.400 m/s has how much momentum?

• 0.1 kg-m/s
• 1 kg-m/s
• 10 kg-m/s
• 100 kg-m/s

In this type of collision, objects tend to "stick" together.

• elastic
• inelastic 
• They "stick" together in both types of collisions

The difference between a car hitting a wall vs. a car hitting a hay stack is

• the Impulse on the car hitting the wall is greater
• the change in momentum of the car hitting the wall is greater
• the force on the car hitting the hay stack is greater
• the collision time of the car hitting the hay stack is greater

Softer landings tend to

• increase impact force
• increase force
• increase collision time
• increase change in momentum

In any collision (crash) the ______ is ALWAYS constant.

• Total Momentum
• total speed
• total Velocity
• Energy
