Flywheel definition and meaning

A flywheel is a mechanical device that stores energy and keeps a vehicle’s engine running smoothly. It is usually made of heavy metal and is mounted on the front of the engine. The flywheel helps to keep the engine speed constant by storing energy from the combustion process and then releasing it as needed. When the engine is running, the flywheel spins rapidly, storing energy in its momentum. This stored energy can be used to help keep the engine running smoothly when there are fluctuations in power output, such as when accelerating or decelerating. Without a flywheel, a car’s engine would have to work harder to maintain a constant speed, which would lead to more wear and tear on the engine and potentially shorter engine life.
