Finding angular acceleration from torque

WebAngular acceleration is inversely proportional to mass. The equation τ = m (r^2)α is the rotational analog of Newton's second law (F=ma), where torque is analogous to force, angular acceleration is analogous to translational acceleration, and mr2 is analogous to mass (or inertia ). Key Terms WebFor rigid bodies, angular acceleration must be caused by a net external torque. …

WebNov 23, 2024 · The definition of torque is not τ = I d ω / d t. We can't even define things like I and ω for rotation that isn't rigid. The definition of torque is τ = d L / d t. So yes, it is possible to have an angular acceleration without an external torque. Your example shows correctly that this can happen.
