Question

The relation between angular momentum and angular velocity is

• A. $\overline{J}=\overline{r}\times \overline{\omega }$
• B. $\overline{J}=\overline{\omega }\times \overline{r}$
• C. $\overline{J}=\frac{I}{\overline{\omega }}$
• D. $\overline{J}=I\overline{\omega }$

Answer 1

Answer: (D)

$\overline{J}=I\overline{\omega }$

By definition the angular momentum $\overrightarrow{J}$ is defined as the product of moment of inertia $I$ and the angular velocity $\overrightarrow{\omega }$.
