A unit of measurement used to quantify time, defined internationally as the duration of a specific number of cycles of radiation associated with the transition between two energy levels in a cesium-133 atom.
A subdivision of a minute in the time measurement system, representing one-sixtieth of a minute and commonly used in indicating time, such as in schedules or clocks.
A measurement used in the context of angles, representing one-sixtieth of a minute and often employed in geographical coordinates to specify latitude and longitude.
Example:
私の時計は１日に５秒進みます。
A hand on a clock or watch that indicates the passing seconds.
The needle or pointer that moves continuously around the dial to show the progression of time in seconds.
The act of announcing the passage of time in second intervals, often used in contexts where precise timing is crucial.

Referring to an interval of time that occurs once each second, often used to describe consistent measurements or rates in contexts such as speed or frequency.
Indicating a repetitive action or occurrence that happens at the pace of one second intervals.
A unit of measurement that specifies the frequency of an event occurring each second, commonly used in scientific or technical contexts to describe speed or data transfer rates.
Example:
光の速度は毎秒約１８万６千マイルである。
