Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Power
Concept:
Classification of scalar and vector quantities.

Solution:
Power is the rate at which work is done. It has only magnitude and does not possess a direction, making it a scalar quantity.

Why other options are incorrect:
  • Torque is a vector pointing perpendicular to the plane of rotation.
  • Momentum is a vector pointing in the direction of the velocity vector.
  • Impulse is a vector representing the change in momentum (pointing in the direction of the net 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.
