2short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.

What is q1?
Show answer
A wheel has rotational inertia 2.02.0 kg\cdotm squared and spins at 5.05.0 rad/s. Calculate its rotational kinetic energy. [2 points]
What is q2?
Show answer
A spinning object's angular velocity triples while its rotational inertia stays the same. By what factor does its rotational kinetic energy change? [1 point]
