Speed is measured in meters per second (m/s), but can also be expressed as kilometers per hour (km/h) or miles per hour (mph). These units quantify how far an object travels within a specific period.

FAQs & Answers

  1. What is the standard unit of speed in physics? The standard unit of speed in physics is meters per second (m/s), which measures how many meters an object travels in one second.
  2. How do kilometers per hour and miles per hour compare? Kilometers per hour (km/h) and miles per hour (mph) are both common units of speed, with 1 mph approximately equal to 1.609 km/h.
  3. Why are multiple units used to measure speed? Different units like m/s, km/h, and mph are used based on the context, region, and convention—scientific measurements prefer m/s, while daily life often uses km/h or mph.
