Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What defines local acceleration?
- Change in velocity over time
- Change in position over time
- Change in velocity due to motion
💡 Hint: Reflect on how speed changes with time at fixed points.
Question 2
True or False: Convective acceleration is solely dependent on time changes.
- True
- False
💡 Hint: Consider the movement of fluid particles across different areas.

Challenge Problems
Push your limits with challenges.
Question 1
Given the velocity profile V(x,y,z) = (3y^2 - z, -2x + z, 5x + 4y), calculate the local and convective acceleration at the point (2, 1, 3).
💡 Hint: Use partial derivatives with respect to each spatial component.
Question 2
A fluid flows through a pipe with varying cross-sections. Explain how local and convective acceleration would change when moving from a wide section to a narrow section.
💡 Hint: Think about how velocity must adapt as forced through a smaller area.
