• ## 10.7: Newton’s Second Law for Rotation - Physics LibreTexts

Recall that the moment of inertia for a point particle is I = mr 2. The torque applied perpendicularly to the point mass in Figure 10.37 is therefore $$\tau = I \alpha \ldotp$$ The torque on the particle is equal to the moment of inertia about the rotation axis times the angular acceleration. We can generalize this equation to a rigid body rotating about a fixed axis.
