Does a soccer ball go faster in the air on a cold or hot day?
Submitted by: AdministratorOn a hot day, the air molecules have more kinetic energy - they move around more freely. They will move out of the way of the soccer ball that is moving through them more easily when the air is warm. In physics we might say that the warmer air is more susceptible to shear force than cooler air. The warmer air will "part" more easily to let the ball pass through.
