Impulse has the same dimensions as which of the following quantities?

Single correct option

A. Force
B. Linear momentum
C. Work
D. Power

Show answer and solution

Answer: (B) Linear momentum

Impulse equals force multiplied by time, which is the change in momentum, so both have unit kg m/s. Force has unit kg m/s², work kg m²/s² and power kg m²/s³, so none of those match.
