Rotational Newton’s second law (fixed axis) (τ = Iα (axis fixed in direction))
jee-mainjee-advancedneet-ug
τ = Iα (axis fixed in direction)
What each symbol means
| Symbol | What it stands for |
|---|---|
| I | Moment of inertia about that axis (kg·m²) |
| α | Angular acceleration (rad/s²) |
| τ_net | Net external torque about axis (N·m) |
When to use this
Axis fixed in inertial frame; I computed about SAME axis. SI: rad measure.
