Question

How is angular momentum related to torque?

Answer 1

`\vec{\tau} = \frac{d\vec{L}}{dt};`
`\vec{L}` - Angular Momentum; `\vec{\tau}` - Torque;

Explanation:

Torque is the rotational equivalent of force and Angular Momentum is the rotational equivalent of Translational Momentum.

Newton's second law relates Translational Momentum to Force,
`\vec{F} = (d\vec{p})/(dt)`

This can be extended to rotational motion as follows,
`\vec{\tau}=(d\vec{L})/(dt)`.

So Torque is the rate of change of Angular Momentum.
