A Flywheel stores kinetic energy in the form of rotational motion. When a force is applied to the flywheel, it accelerates and stores energy. When the force diminishes or fluctuates, the flywheel releases the stored energy to maintain the rotation's momentum.Attributes:• Reduce fluctuations in speed and power output.• Provide stability by smoothing out the rotation of a machine or engine.• Maximize its moment of inertia to store as much energy as possible.Applications: A Flywheel is used to provide stability and kinetic energy storage. They are used in automotive engines to ensure smooth power delivery, in power generation systems for grid stability, and in heavy machinery for consistent operation.
