"Reading Questions" come straight from the wording on the website/source.
"Application Questions" are NOT on the websites and require you to apply the information/critically think.

*How are static friction and sliding friction connected in this specific scenario?
*How does static friction behave as more force is added to a stationary object?
*How does sliding friction behave as more force is added to a moving object?
*Why was fluid friction discounted for this scenario?
*Construct a neat, organized data table for 5 objects that includes all necessary information.

Answer the following questions on a piece of notebook paper using complete sentences. Group work may be submitted.
Simulation
1. What is momentum?
2. Describe what happens in the simulation when the bumper is "Bouncy." Do the same for when it is "Locking."
*Set the bumper completely to the right (i.e. “Locking”).
*Set the mass of the blue car to 300 kg and the mass of the red car to 200 kg.
**Make sure that these settings stay this way for the next 4 questions.
3. Which car (if any) wins when the blue car has a velocity of 1 m/s and the red car has a velocity of -1 m/s? What does this indicate about their momentums prior to the collision?
4. Which car (if any) wins when the blue car has a velocity of 1 m/s and the red car has a velocity of -2 m/s? What does this indicate about their momentums prior to the collision?
5. Which car (if any) wins when the blue car has a velocity of 1 m/s and the red car has a velocity of -3 m/s? What does this indicate about their momentums prior to the collision?
6. What happens if both cars have their velocities set to 1 m/s?
Reason and Apply
7. Explain why a large truck will have more momentum than a small car, assuming that they are moving at the same velocities.
8. In order for the small car to have more momentum, what needs to happen to the velocities of each vehicle?
Use the definitions below for the next 2 questions:
Elastic – describes a collision where the objects bounce off of each other; “Bouncy”
Inelastic – describes a collision where the objects become stuck together ; “Locking”
9. Consider two objects with equal momentums. Describe how they will behave in an elastic collision. Do the same for an inelastic collision.
10. Consider two objects with vastly different momentums. Describe how they will behave in an elastic collision. Do the same for an inelastic collision.
