Which of the following physical quantities has the same dimensional formula as impulse?

A. Momentum✓ Correct Answer
B. Work
C. Pressure
D. Surface tension

💡 Solution & Explanation

Impulse is defined as the product of force and time interval, which yields the dimensions of mass times velocity, matching the dimensional formula of linear momentum. Other physical quantities like work possess dimensions of energy, pressure represents force per unit area, and surface tension is force per unit length. The impulse-momentum theorem establishes that the net impulse acting on an object equals the total change in its linear momentum.
