Official Correct Choice:
Option D: Velocity-time graph
Concept:

Definition of acceleration through kinematics.

Solution:

  • Acceleration is the rate of change of the velocity vector over time (\( \vec{a} = \frac{\Delta \vec{v}}{\Delta t} \)).


  • The gradient (slope) of a velocity-time graph mathematically plots this exact \( \frac{\Delta y}{\Delta x} \) ratio.


Why other options are incorrect:

Displacement-time gives velocity. Speed-time gives magnitude of acceleration but lacks the crucial directional vector data required for true acceleration.

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.
