Misunderstanding Atmospheric Pressure Changes
Students often think that atmospheric pressure decreases linearly with altitude, rather than understanding that it decreases exponentially due to the decreasing density of air.
Fix itTo fix this, students should visualize and study the relationship between altitude and air density, recognizing that as altitude increases, the number of air particles decreases, leading to a more rapid decrease in pressure. In Atmospheric pressure (physics only), correct the mistake by naming the relevant force or motion quantity and checking force and pressure.
