Question

The sign (+ ve or $-$ ve $)$ of the average velocity depends only upon

• A. the sign of displacement
• B. the initial position of the object
• C. the final position of the object
• D. None of the above

Answer 1

Answer: (A)

Since, average velocity, $\bar{v}=\frac{\Delta x}{\Delta t}=\frac{\text{ Displacement }}{\text{ Time interval }}$
Thus, average velocity depends on the displacement and hence, it can be positive or negative depending upon the sign of the displacement.
