- B. metres per second
- C. kilometres per hour
- D. newtons
Answer
metres per second squared
Explanation
Acceleration is defined as the rate of change of velocity, and it is measured in metres per second squared (m/s²).
Common mistake
Unit mismatch in uniform acceleration calculations
Students often mix metres per second with kilometres per hour for velocity while keeping acceleration in m/s² and distance in metres, leading to incorrect results
Always convert all velocities to the same unit (e.g. m/s) before using v²‑u² = 2as, and ensure distance is in metres and acceleration in m/s²
