Conservation of angular momentum (L conserved if τ_ext = 0 about same point/axis)
jee-mainjee-advancedneet-ug
L conserved if τ_ext = 0 about same point/axis
What each symbol means
| Symbol | What it stands for |
|---|---|
| L | Angular momentum |
| τ_ext | Net external torque |
When to use this
No net external torque about an axis → L component on that axis conserved.
