Storing energy in a heavy spinning wheel exploits rotational kinetic energy in a device called a:
AFlowmeter
BFloodgate
CFlywheel
DFreewheel
Answer & Solution
Correct answer: C. Flywheel
1. The wheel is given a large moment of inertia.
2. Spinning it fast stores considerable energy.
3. That device is a flywheel.
