Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Force, acceleration
Concept:

According to Newton's Second Law of motion, the relationship between net force and acceleration is rigidly governed by a scalar mass.

Formula:

$$ \vec{F}_{net} = m\vec{a} $$

Solution:

  • Mass (\( m \)) is a strictly positive scalar value.


  • When a vector (\( \vec{a} \)) is multiplied by a positive scalar, the resulting vector (\( \vec{F} \)) MUST point in the exact same direction.


  • Therefore, the net force and the acceleration it produces are permanently and flawlessly aligned in direction.


Why other options are incorrect:

Displacement and velocity vectors tell you where an object is going, not where it is being pushed. For example, a car braking has forward velocity but backward force.

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.
