A flywheel's large moment of inertia lets it resist sudden changes in:
AScale
BSpeed
CShape
DShade
Answer & Solution
Correct answer: B. Speed
1. Inertia resists change, in rotation as in translation.
2. For a spinning wheel the quantity resisting change is its rate of turning.
3. Because of its large moment of inertia, the flywheel resists sudden increase or decrease of speed.
4. So the answer is speed.
