Angular Momentum and Angular Impulse

AP Physics 1· difficulty 1/5

Angular momentum has units

  • A

    kg/m\text{kg/m}

  • B

    kg⋅m2/s\text{kg·m}^2/\text{s}

    check_circle
  • C

    kg⋅m2/s2\text{kg·m}^2/\text{s}^2

  • D

    N⋅m\text{N·m}

Explanation

[L]=[I][ω]=kg⋅m2⋅rad/s=kg⋅m2/s[L] = [I][\omega] = \text{kg·m}^2 \cdot \text{rad/s} = \text{kg·m}^2/\text{s} (rad is dimensionless).
