Question 1.
Define local acceleration.
Show hintHide hint
Think about acceleration at a traffic signal.
Question 2.
What does convective acceleration refer to?
Show hintHide hint
Consider how a raindrop moves down a window.
3Question 3.
What is local acceleration?
- A. Acceleration due to the movement of particles
- B. Change in velocity at a point over time
- C. Acceleration in a gravitational field
Show hintHide hint
Think about changes in speed at a single location.
4Question 4.
What does convective acceleration depend on?
- True
- False
Show hintHide hint
Remember, it’s about motion through variable speeds.
Question 5.
A fluid particle moves with an initial velocity of 3 m/s and experiences a local acceleration of 2 m/s² over 5 seconds. Calculate the final velocity and also determine if there is a convective acceleration present if the particle is at rest initially.
Show hintHide hint
Use the basic kinematic equations.
Question 6.
Given a situation where a fluid particle experiences local acceleration of 4 m/s² and convective acceleration of 3 m/s². What is the total acceleration, and explain the physical significance of each component?
Show hintHide hint
Consider both effects on fluid particles during flow.
