Is dyne the SI unit of momentum?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
No, dyne is not the SI unit of momentum. Dyne is the CGS unit of force, not momentum. The SI unit of momentum is kilogram meter per second (kg·m/s). However, in the CGS system, momentum is measured in gram centimeter per second (g·cm/s), which can also be expressed as dyne-seconds since 1 dyne·s = 1 g·cm/s.
