Parasite drag decreases with an increase in velocity. This statement is:

Parasite drag actually increases with an increase in velocity. This type of drag consists of form drag and skin friction drag, both of which are influenced by speed. As the velocity of an object moving through a fluid increases, the relative wind speed increases as well, leading to a rising drag force due to both the increased pressure differences around the object (form drag) and higher friction on the surface (skin friction drag).

In the case of higher speeds, the drag force becomes more significant, and it is a critical factor that must be managed in aerodynamic design to ensure efficient performance. Parasite drag is generally significant in fast-moving aircraft, where every bit of drag can impact fuel efficiency and performance. Therefore, the idea that parasite drag decreases with an increase in velocity is not accurate, thus leading to the conclusion that the statement is false.
