Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Constant
Concept:

Graph interpretation requires knowing what the slope physically represents.

Solution:

  • The slope of a displacement-time graph mathematically equals velocity (\( v = \frac{\Delta d}{\Delta t} \)).


  • If a line has a strictly constant slope (a straight line), then the value it represents (velocity) must also be completely constant.


Why other options are incorrect:

Variable velocity would require a curved line (changing slope). Infinite velocity is physically impossible.

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.
