The acceleration of a particle moving with terminal velocity through a fluid is Options:
Correct answer: C. Zero
- A. Positive
- B. Negative
- C. Zero
- D. Cannot produce
Explanation
When a particle reaches terminal velocity in a fluid, it means that the gravitational force pulling it down is balanced by the drag force acting upwards. At terminal velocity, the net force on the particle is zero, so its acceleration is zero as well.

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
