* Analog clocks: These clocks use hands to indicate the time. The hour hand moves once every hour, while the minute hand moves once every minute.
* Digital clocks: These clocks display the time in numbers. The numbers change every minute, and some digital clocks also display the seconds.
* Atomic clocks: These clocks are the most accurate clocks in the world. They use the vibrations of atoms to measure time, and are accurate to within a few billionths of a second.
