Question 1.
What does Newton's Second Law state?
Show hintHide hint
Remember the formula: F = ma.
Question 2.
Define local acceleration in your own words.
Show hintHide hint
It focuses on one location.
3Question 3.
What is the formula for Newton's Second Law?
- F = m/a
- F = ma
- F = m + a
Show hintHide hint
Focus on the relationship between force and motion.
4Question 4.
True or False: Convective acceleration is solely dependent on time.
- True
- False
Show hintHide hint
Consider how particles experience variable velocities.
Question 5.
A fluid particle moves through a region where the velocity field changes. Given the velocity function V = (x^2 + y^2)i + (3xy)j, calculate the local and convective acceleration at the point (1, 2).
Show hintHide hint
Use the derivatives of the components of the velocity function and apply the necessary transformations.
Question 6.
In a steady-flow scenario where the velocity field is represented as V = (4x - y)i + (10 - z)j, establish the conditions for local and convective terms, and demonstrate their calculation.

Look carefully at how the rate of change is influenced by fixed versus moving boundaries.
