Quick questions on Rotational kinetic energy - AP Physics C: Mechanics Unit 6
3short 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 flywheel with kg m squared spins at rad/s. Calculate its rotational kinetic energy. [2 points]
What is q2?Show answer
Explain why a solid disk rolls down a ramp faster than a hoop of the same mass and radius. [2 points]
What is not using for rolling?Show answer
The rolling constraint links the two energies; without it you have two unknowns.
