Physics - Rotation Question with Solution | TestHub

P. Angular momentum of a particle about the origin is $\vec{L}=\vec{r}\times \vec{p}$. Q. The magnitude of angular momentum of a rigid body rotating about a fixed axis is $L=I\omega$.

R. The principle of conservation of angular momentum states that if the net external torque is zero, then ${\vec{L}}_{initial}={\vec{L}}_{final}$. S. The relation between net external torque and angular momentum is ${\vec{\tau }}_{ext}=\frac{d\vec{L}}{dt}$.
