Angular impulse from torque time
A constant external torque of \(13\,\text{N m}\) acts on a rotor in a flywheel storage investigation for \(8\,\text{s}\). Calculate the change in angular momentum. Read the diagram before calculating the requested value. Enter the numerical result and choose the interpretation that matches the physics meaning.
Worked practice: physics data and result
Read the physical quantities first, then calculate the result and state what it means.
