Momentum Quiz

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

• size and shape
• mass and speed
• mass and veloctiy
• mass and energy

The equation to calculate momentum is

• p = m x v

• p = 1/2 m x v²

• p = m x g x h

• p = m x g

Determine the momentum of 1000-kg car moving southward at 20 m/s......... 

• 20000 N
• 20000 Joules
• 20000 Kg * m/s south
• 10000 kg * m/s south

What is the unit for momentum?

• m/sec

• kg/sec

• kg/m

• kg x m/sec

What is the unit for velocity?

• m/sec

• kg/sec

• kg/m

• kg x m/sec

A 50 kg ball rolls down the street at 5 m/s. Calculate the momentum of the ball. 

• 55 kg*m/s
• 100 kg*m/s
• 250 kg*m/s
• 500 kg*m/s

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

• Inelastic

• Elastic

The Law of Conservation of Momentum states:

• The total momentum before a collision is equal to the total momentum after a collision.

• The total momentum before a collision is greater than the total momentum after a collision.

• The total momentum before a collision is less than the total momentum after a collision.

• The total momentum before a collision is not related to the total momentum after a collision.

A 10-kg toy truck moves at 5 m/s East. It collides and bounces off of a 5-kg toy car moving 10 m/s moving West. Which equation would you use to solve for the final velocity of the car?

A 10-kg toy truck moves at 5 m/s East. It collides head-on with a 5-kg toy car moving 10 m/s moving West. What is the total momentum of the system?

• 0 kg·m/s

• 30 kg·m/s

• 50 kg·m/s 

•  10 kg·m/s
