A "Flywheel" is a mechanical device that stores rotational energy. It consists of a heavy wheel that spins at high speeds, allowing it to maintain momentum. This stored energy can be released when needed, providing a steady power output. Flywheels are commonly used in various applications, including electric vehicles and energy storage systems. In business, the term "flywheel" describes a self-reinforcing cycle that drives growth. As a company invests in customer satisfaction and product quality, it attracts more customers, leading to increased sales and further investment. This creates a continuous loop of improvement and success, similar to how a physical flywheel maintains its motion once set in motion.
