Terminal Velocity Formula. In the case of raindrops, initially, it is due to gravity that it accelerates. As the velocity increases, the retarding force also increases. Finally, when viscous force and the buoyant force is equal to the force due to gravity, the net force becomes zero, and so it does the acceleration. The raindrop then falls with a constant velocity, known as terminal velocity.

What is Terminal Velocity? Terminal velocity is defined as the highest velocity attained by an object falling through a fluid. It is observed when the sum of drag force and buoyancy is equal to the downward gravity force acting on the object. The acceleration of the object is zero as the net force acting on the object is zero.
