When two objects are in free fall (ignoring air resistance), their motion is governed by the force of gravity. The following points are relevant:
Acceleration: All objects experience the same acceleration due to gravity (g = 9.8 m/s2) regardless of their mass.
Momentum: Momentum (p) = mass × velocity. Since the bodies have different masses, their momenta will differ.
Kinetic Energy: KE = (1/2) × mass × velocity2. As mass differs, so does kinetic energy.
Potential Energy: PE = mass × g × height. Again, different masses result in different potential energies.
∴ The only quantity equal for both bodies is acceleration.
∴ The correct answer is Option 2: Acceleration.
