Spring-powered mechanisms use the energy stored in a compressed or stretched spring to perform work. When the spring is released, it converts potential energy into kinetic energy, allowing it to move objects or perform tasks. Common examples include watches, toys, and mechanical clocks. These mechanisms are often simple and efficient, relying on the elasticity of materials like metal or plastic. They can be found in various applications, from automotive systems to industrial machinery. The design and tension of the spring determine the force and speed of the movement, making them versatile for different uses.
