Question

Quizplus · Accepted Answer

During a vertical dive, especially just before coming up from the bottom, the pilot experiences an upward force greater than gravity (g) due to the centripetal acceleration required to change the direction of the plane from downward to upward. This results in a sensation of increased weight or force acting on the pilot in the upward direction.
