Which of the following is NOT true about a flywheel?
- Flywheels store momentum.
- Flywheels represent a circular process rather than a linear one.
- Flywheels are able to stand unsupported for an indefinite amount of time.
- Flywheels accelerate as you add more energy to them.
Explanation: The statement ‘Flywheels are able to stand unsupported for an indefinite amount of time’ is NOT true about a flywheel. A flywheel, in the context of the inbound methodology, is a metaphor representing a continuous and interconnected process where momentum builds over time. However, in physical terms, a flywheel does require support to maintain its position and function effectively. While flywheels are designed to store and release rotational energy to smooth out fluctuations in speed or provide continuous motion, they rely on external support structures such as bearings or shafts to remain stable and operational. Without proper support, a flywheel would not be able to maintain its position or fulfill its intended function. Therefore, the correct answer is Flywheels are able to stand unsupported for an indefinite amount of time, as this statement does not accurately reflect the physical properties or requirements of a flywheel. The other options provided are true characteristics of a flywheel, such as storing momentum, representing a circular process, and accelerating as more energy is added, making them incorrect choices for this question.
