How Does a Clock Measure Time Without Electricity?

Imagine a clock that doesn’t need batteries or wires, it just keeps ticking on its own. A mechanical clock uses springs and gears, like the wheels of a toy car. When you wind it up, energy is stored in the spring, which then pushes the gears to move, making the hands turn, tick-tock, all day long! Just like when you stretch a rubber band and let it go, the spring works the same way: it stores energy and slowly releases it as time goes on. That’s how clocks keep working even without electricity.
