How Does a Clock Measure Time Exactly?

Imagine a clock like a super-fast drummer who never misses a beat. A clock uses special parts, like a pendulum or a tiny crystal, to keep time exactly by counting every little tick and tock. The better the drumming, the more accurate the time! ## How It Works When you hear a clock tick, it’s counting one second. Some clocks use something called a quartz crystal that vibrates really fast, like a tiny super-fast drummer inside the clock. Every vibration is counted as a tick, and that’s how clocks know exactly what time it is.
