Clocks are like little machines that count steps. Just like you can count how many times you blink to know how long a minute feels, clocks use tiny movements, like the ticking of gears or the swinging of a pendulum, to measure time accurately. Some even use light bouncing back and forth really fast!
Examples
- A pendulum clock keeps time by counting how many times its swing takes exactly one second.
- Your phone's clock uses a tiny crystal that vibrates millions of times each second.
- An atomic clock is like a super-accurate metronome for the whole world.
