Show hintHide hint
What does F represent in the equation?
Question 2.
What is a vector quantity?
Show hintHide hint
Think about how we describe forces.
3Question 3.
What is the formula for Newton's second law?
- F = ma
- F = mv
- F = m/a
Show hintHide hint
Think about how force is related to mass and acceleration.
4Question 4.
Is local acceleration time-dependent?
- True
- False
Show hintHide hint
Consider what 'local' implies.
Question 5.
A fluid particle is accelerating in various directions in a 3D flow field. Describe how you would use both local and convective accelerations to analyze the particle's motion. Provide examples.
Show hintHide hint
Think about how velocities are measured over time versus across a spatial gradient.
Question 6.
Explain how you would determine the material derivative for a fluid property such as temperature in a scenario where the fluid is heated from below. Describe the steps.
Show hintHide hint
Consider both temporal and spatial changes in temperature.
