Common mistake
Misinterpreting Stopping Distance Graphs
Students often misinterpret the trends in graphs showing stopping distances, confusing the relationship between speed and stopping distance.
To fix this, students should focus on understanding that as speed increases, stopping distance increases significantly due to the squared relationship between speed and kinetic energy.
