Imagine a clock as a little robot inside a box. When you wind it up, it stores energy in a spring like a coiled snake. As the spring unwinds slowly, it turns gears that make the hands move, just like walking without running. The more you wind it, the longer it keeps time!
Examples
- Winding your grandfather's clock every morning keeps it running all day long.
- A wind-up toy car moves forward because of the spring you twist before letting go.
- Pulling a weight down on a grandfather clock makes the hands move without electricity.
