Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Parallel
Concept:

Multiplying a vector by a strictly positive scalar preserves its direction entirely.

Formula:

$$ \vec{p} = m\vec{v} $$

Solution:

  • Mass (\( m \)) is an intrinsically positive scalar quantity.


  • When the velocity vector (\( \vec{v} \)) is multiplied by mass, the resulting momentum vector (\( \vec{p} \)) is scaled up, but its geometric direction is untouched.


  • Therefore, momentum ALWAYS points exactly in the same direction as velocity. Vectors in the same direction are parallel.


Why other options are incorrect:

Antiparallel would require a negative mass, which does not exist in classical physics.

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.
