Question
- A. Metres per second (m/s)
- B. Metres per second squared (m/s²)
- C. Kilometres per hour (km/h)
- D. Joules (J)
Answer
Metres per second squared (m/s²)
Explanation
Acceleration is defined as the rate of change of velocity and is measured in metres per second squared (m/s²).
Common mistake
Misunderstanding the Uniform Acceleration Equation
Students often confuse the variables in the equation v² - u² = 2as, leading to incorrect calculations of final velocity, initial velocity, acceleration, or distance.
To fix this, students should carefully identify each variable: v is final velocity, u is initial velocity, a is acceleration, and s is distance. Practicing with example problems can help reinforce the correct application of the equation.
