Terminal velocity is_____________?
Correct answer: C. Uniform and maximum
- A. Uniform
- B. Maximum
- C. Uniform and maximum
- D. Neither uniform nor maximum
Explanation
Terminal velocity is reached when the upward drag force balances the downward weight, so the resultant force and acceleration become zero. The body then moves with constant speed, and this speed is the maximum steady speed possible in the given fluid. Students may choose “uniform” alone by noticing the constant speed but overlooking that terminal speed is also the limiting maximum.

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.
