Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Force
Concept:

This is the fundamental definition of Newton's Second Law in terms of momentum.

Formula:

$$ F = \frac{\Delta P}{\Delta t} $$

Solution:

  • The rate at which an object's momentum changes is strictly equivalent to the net applied external force.


Why other options are incorrect:

Acceleration is the rate of change of velocity. Work is Force times displacement.

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.
