Physics PYQ 24 of 144 · Gravitation

Two objects of different masses falling freely near the surface of the Moon would

  1. Ahave different accelerations
  2. Bundergo a change in their inertia
  3. Chave same velocity at any instant
  4. Dexperience forces of same magnitude

69th BPSC

Show answer and explanation

Correct answer: (c) have same velocity at any instant

Explanation

In free fall, acceleration equals acceleration due to gravity (g) and is completely independent of an object's mass.

Starting from rest (u = 0), velocity follows v = gt, so both objects gain the same velocity at any instant.

This rules out different accelerations or unequal forces (heavier mass feels a larger force, but also has more inertia, keeping g constant).
