What is a Flywheel?

Flywheel is generally applied in energy storage systems to keep up with the energy in the system as rotational energy. Providing energy at higher rates than the limit of the energy source. This is done by getting energy in a flywheel after some time. Then, at that point, releasing it rapidly at rates that surpass the energy source''s capabilities.

ELI5:What does a flywheel do and how does it work?

A flywheel is a heavy round weight attached to the shaft of an engine. It maintains rotational inertia, meaning it takes energy to make it spin, but once it is spinning it wants to keep spinning. It is basically a top or a beyblade. For engines with a few pistons, the flywheel helps keep things spinning smoothly.
