Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Mechanical energy
Concept:

An object in motion intrinsically possesses Kinetic Energy, which is a form of Mechanical Energy.

Formula:

$$ M.E = K.E + P.E $$

Solution:

  • Because the car is moving, it has velocity, giving it \( \frac{1}{2}mv^2 \).


  • Kinetic energy is categorized broadly as Mechanical energy.


Why other options are incorrect:

While a car produces heat and sound, and uses chemical energy (fuel), its pure state of gross physical motion is represented entirely by Mechanical energy.

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.
