Question 1.
What is conservation of momentum?
Show hintHide hint
Think about the implications of no outside forces.
Question 2.
What does a control volume represent?
Show hintHide hint
It helps visualize where fluids enter and exit.
3Question 3.
What does the conservation of momentum state?
- Momentum increases over time
- Momentum decreases without constraint
- Total momentum remains constant in a closed system
Show hintHide hint
Consider a ball rolling on a smooth surface.

- True
- False
Show hintHide hint
Think about gravitational forces operating in fluids.
Question 5.
