What Does 10 km per Hour per Second Mean? Understanding Acceleration Explained

Learn what 10 km per hour per second means and how it represents acceleration, not speed, with easy examples in this short Q&A video.

10 km per hour per second is a measure of acceleration, not speed. It means that an object's speed increases by 10 kilometers per hour every second. It's a rate at which velocity changes over time. For instance, if a vehicle accelerates at this rate, it would go from being stationary to a speed of 10 km/h in one second, 20 km/h in two seconds, and so on.

FAQs & Answers

  1. What is acceleration measured in? Acceleration is measured as the rate of change of velocity over time, typically in units like meters per second squared (m/s²) or kilometers per hour per second (km/h/s).
  2. How is 10 km per hour per second different from speed? 10 km per hour per second measures acceleration, meaning velocity increases by 10 km/h every second, whereas speed is the rate of motion regardless of time change.
  3. Can acceleration be negative? Yes, negative acceleration, often called deceleration, indicates an object is slowing down as its velocity decreases over time.
