IB skill practice

Apply angular momentum conservation

Paper 1, Paper 2 5 marks Difficulty 4

Angular momentum from inertia and angular speed

A rotor in a robot arm laboratory trial has moment of inertia \(2\,\text{kg m}^{2}\) and angular speed \(11\,\text{rad s}^{-1}\). Calculate the angular momentum. 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.
