Common mistake
Unit Conversion Confusion
Students often confuse the conversion factors between metres per second (m/s) and kilometres per hour (km/h), leading to incorrect calculations.
Remember that to convert from m/s to km/h, you multiply by 3.6, and to convert from km/h to m/s, you divide by 3.6.
