Official Correct Choice:
Option C: Average velocity
Concept:

Kinematic definitions rely on whether a quantity is measured over an interval or at a specific moment.

Formula:

$$ \vec{v}_{avg} = \frac{\text{Total } \Delta \vec{x}}{\text{Total } \Delta t} $$

Solution:

  • Dividing the total net displacement covered during an entire journey by the total elapsed time yields a single summarizing value.


  • This macro-level calculation is the formal definition of average velocity.


Why other options are incorrect:

Instantaneous velocity is measured at a precise moment (\( \Delta t \to 0 \)). Uniform and variable velocities are states of motion, not defined merely by a bulk division formula.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
