Understanding 速度 (そくど)
The word 速度 means "speed" or "velocity" and is commonly used to describe how fast something moves or operates. It can refer to physical speed, like a car or a person running, as well as abstract speeds, such as internet connection speed or work pace.
Common Contexts
- Vehicles and transportation: 車の速度 (car speed)
- Technology: インターネットの速度 (internet speed)
- Work or task pace: 仕事の速度 (work speed)
Collocations and Patterns
- 速度を落とす: to reduce speed, often used in driving or machines.
- 速度が速い／遅い: speed is fast/slow, describing the rate of movement or progress.
- 速度を上げる: to increase speed.
Usage Notes
速度 is a more formal or technical term compared to はやさ (速さ), which also means speed but is more general and often used in everyday conversation. When talking about speed in scientific, technical, or official contexts, 速度 is preferred.
Learners sometimes confuse 速度 with 速さ; remember 速度 often appears in contexts involving measurement or quantification of speed.
Summary
Use 速度 when discussing measurable or technical speed, especially in transportation, technology, or work contexts. Pair it with verbs like 落とす (to reduce) or 上げる (to increase) to describe changes in speed.
