Unit for momentum

    Units of Momentum

    Is kg·m/s the proper unit for momentum? Can it also be expressed as ( kg·m/s² )?

    kg·m/s is correct.

    kg·m/s² cannot be a unit of momentum--it's a unit of force equivalent to 1 N.

    1. One form of the proper metric unit for momentum is

    a. (N·sec) b. (kg·m) c. (kg·m/s²) d. (Joule)

    I know that kg·m/s is a unit for momentum, but can it also be expressed as kg·m/s²?
