All of the following are the factors on which terminal velocity of a falling object depends EXCEPT
Correct answer: B. Velocity of the object.
- A. Mass of the object.
- B. Velocity of the object.
- C. Cross-sectional area of the object.
- D. Gravitational acceleration of the object.
Explanation
The correct answer is Option B:Velocity of the object.Terminal velocity is the constant speed achieved when the force of gravity is balanced by the drag force, so it does not depend on the velocity of the object itself. The mass of the object, cross-sectional area, and gravitational acceleration are all factors that influence the forces involved in reaching terminal velocity. Mass affects the gravitational force, the cross-sectional area affects the drag force, and gravitational acceleration influences the overall gravitational pull on the object.

About Terminal Velocity
Terminal velocity is the constant speed reached when gravitational force is balanced by fluid resistance. The topic covers drag, buoyant force, the conditions for zero acceleration, and how viscosity, object size, shape and density affect the limiting speed, with a distinction between free fall before and after terminal velocity.
