"Spring-powered" refers to a mechanism that uses a coiled spring to store and release energy. When the spring is compressed or stretched, it stores potential energy. Once released, this energy can be transformed into kinetic energy, causing movement. This principle is commonly found in toys like wind-up cars and tools such as mechanical watches. In everyday life, spring-powered devices are efficient and reliable. For example, spring-loaded toys can jump or pop up when the spring is released. Similarly, bicycles often use spring mechanisms in their suspension systems to absorb shocks, providing a smoother ride on uneven surfaces.
