    Question

    The SI unit of angular momentum is equivalent to which

    of the following?
    A kg⋅m²/s Correct Answer Incorrect Answer
    B kg⋅ m/s² Correct Answer Incorrect Answer
    C kg⋅ m²/ s² Correct Answer Incorrect Answer
    D kg⋅m/s Correct Answer Incorrect Answer

    Solution

    Angular momentum (L) is given by:                       L=Iω=mvr Since moment of inertia I has units kg.m² , and ω (angular velocity) has units 1/s, the SI unit of L is:                       Kg. m² /s
