The rain drop falling from the sky reach the ground with
Correct answer: B. terminal velocity
- A. constant acceleration
- B. terminal velocity
- C. constant pressure
- D. variable acceleration
Explanation
As a raindrop falls, it speeds up due to gravity. But as it falls faster, air resistance slows it down. Eventually, it reaches a constant speed where gravity and air resistance balance out. This constant speed is called terminal velocity

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.
