Newtonian impulse concept: Equal force applied for equal time on different masses. Two bodies of different masses, both initially at rest, are acted upon by the same constant force for the same duration. What common physical quantity do they acquire? Choose the correct option.

Difficulty: Easy

Correct Answer: Equal change in momentum (same momentum after push)

Explanation:

Given data

Concept/Approach
Impulse–momentum theorem: Impulse = F·t = change in momentum.

Step-by-step
Impulse on body 1 = F·t; impulse on body 2 = F·t (same).Since both start from rest, final momentum of each = F·t.

Common pitfalls
Acceleration depends on mass (a = F/m), so not equal; velocities and kinetic energies also differ.
