Air resistance, the opposing force caused by air, slows down falling objects. As objects move through air, they experience drag due to friction with air particles. This resistance increases with the object’s cross-sectional area and decreases with its streamlined shape. Eventually, air resistance reaches an equilibrium with gravity, resulting in terminal velocity, the constant speed…
