Momentum Loss Review

The total momentum of two colliding object stays the same after a collision. Is the definition for?

• Conservation of momentum
• Kinetic energy loss
• Energy conservation
• Momentum transfer

In a reared collision the front car loses the most momentum.

• True
• False

When you add the momentums together it is called (a)   momentum

The right moving car will always be ​ (a)   while the left moving car is ​ (b)   . If both cars are moving at the same speed and weigh the same their total momentum will be​ (c)  

• positive
• negative
• zero
• fast
• slow
• large

If two cars of the same weight get into a head on accident. If the car moving right as a momentum of 180 000 kg.km/h and the car moving to the left has a 170 000 kg.km/h momentum. What is the total momentum?

Mathematical Equivalence

ON

In the previous question which way do the cars go after the collision

• Right

• Left

You witness a head on collision between a semi truck and a pick up truck. With you knowledge of momentum you understand that the Semi truck will have more because it is heavier. You estimate that the Semi had a momentum of 1 000 000 kg.km/h going left. While the pickup truck only had a 250 000 kg.km/h going right.

What is the total momentum? Ignore the negative
