The dimension of impulse is the same as that of

(A) Volume
(B) Momentum
(C) Torque
(D) Change in the rate of momentum

Correct Answer : Momentum
Question Asked : SSC Section Officer (Audit) Exam 1997
Explanation : Impulse = Force x Time Hence, the dimension of impulse are same as that of momentum. If a heavy truck moving fast has a large momentum-it takes a large and prolonged force to get the truck up to this speed, and it takes a large and prolonged force to bring it to a stop afterwards. If the truck is lighter or moving slower, then it would have less momentum i.e. both mementum and impulse being dependent on mass and speed.
