What is the unit and dimension of linear momentum?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The SI unit of linear momentum is kilogram meter per second (kg·m/s) or euivalently, newton-second (N·s). The dimensional formula is [MLT⁻¹], where M represents mass, L represents length, and T represents time. In the CGS system, the unit is gram centimeter per second (g·cm/s). Understanding these units is essential for solving physics problems correctly.
