Question 1
A figure skater with a moment of inertia of 5 kgm² spins with an angular velocity of 2 rad/s. The skater pulls in their arms, reducing their moment of inertia to 2 kgm². What is their new angular velocity?
💡 Hint: Remember to apply the conservation formula correctly.
Question 2
Analyze how the conservation of angular momentum is essential in satellite motion and relate it to changes in orbital distance.
💡 Hint: Consider the effect of distance on orbital speed.
