Question
Define acceleration and explain how it is measured.
Answer
Acceleration is defined as the rate of change of velocity of an object. It is measured in metres per second squared (m/s²).
Explanation
This question tests the student's understanding of the concept of acceleration and its units, which is fundamental in the study of forces and motion.
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.
