The physical quantity that has the same dimensional formula as impulse is momentum.

Quick Scoop

  • Impulse =Force×time=\text{Force}\times \text{time}=Force×time, so its dimensions are MLT−1MLT^{-1}MLT−1.
  • Momentum =mass×velocity=\text{mass}\times \text{velocity}=mass×velocity, which also has dimensions MLT−1MLT^{-1}MLT−1.
  • Therefore, among common options like work, power, force, etc., the correct answer to “which of the following physical quantities has the same dimensional formula as impulse” is momentum.

If your question was MCQ-type, you should mark option (A) Momentum.
