Question 1
A sphere and a cube have the same mass but different shapes. Compare their moments of inertia when rotating about an axis through their center.
π‘ Hint: Consider how evenly mass is distributed.
Question 2
A rigid body with a moment of inertia tensor \( \mathbf{I} \) rotates about an axis defined by \( [0;31m\hat{k}\) with a constant angular velocity. Discuss how the conservation of angular momentum applies.
π‘ Hint: Reflect on the relationship between torque and change in angular momentum.
