The fluid friction acting on a body is inversely proportional to the relative speed between the object and liquid surface.
AnswerClick to flip back
A
False
💡 Explanation:
Fluid friction (drag force) is directly proportional to relative velocity at low speeds (Stokes' law: F = 6πηrv) and proportional to the square of velocity at higher speeds (F = ½ρv²CdA). It is never inversely proportional to speed - as speed increases, drag force always increases, not decreases. Therefore, the statement is false.
