Flywheel
quote
A mental model that captures this process well is the flywheel, a rotating physical disk that is used to store energy. Flywheels are still used in many industrial applications, though a more relatable example to get the concept is a children's merry-go-round. It takes a lot of effort to get a merry-go-round to start spinning, but once it is spinning, it takes little effort to keep it spinning.
