Question
- A. Metres per second (m/s)
- B. Metres per second squared (m/s²)
- C. Kilometres per hour (km/h)
- D. Newton (N)
Answer
Metres per second squared (m/s²)
Explanation
Acceleration is measured in metres per second squared (m/s²), which indicates how much the velocity changes per second.
Common mistake
Confusing acceleration with speed
Students often treat acceleration as a speed value and use the same units (m/s) instead of m/s²
Remember acceleration is the rate of change of velocity, so its unit is metres per second squared (m/s²). When applying acceleration equations, always check that the result is expressed in m/s², not m/s.
