Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Independent of each other
Concept:

Galilean independence of orthogonal vectors.

Solution:

  • A core tenet of projectile physics is that perpendicular motion vectors do not influence one another.


  • Gravity only accelerates an object downward. It has strictly zero effect on the horizontal velocity.


  • Therefore, the vertical rise and fall is completely mathematically independent of how fast the object moves horizontally.


Why other options are incorrect:

If they were dependent, a faster horizontal speed would alter the time it takes to fall to the ground, which Galileo famously proved false.

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.
