Question

When net force acting on a droplet becomes zero, its constant speed is known as?

Answer 1

Answer

No.

According to Newton's first law of motion :

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

So acceleration can only occur when the forces acting on an object are unbalanced.

Therefore if the net force is zero, acceleration can not occur.

Answer 2

Answer:

Since the net force on the object is zero, the object has zero acceleration. In fluid dynamics, an object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the fluid through which it is moving.
