What is dynamic lift ?
Dynamic lift is the force that acts on a body, such as airplane wing, a hydrofoil or a spinning ball, by virtue of its motion through a fluid.
In many games such as cricket, tennis, base-ball, or golf, when a spinning ball deviates from its parabolic trajectory and move through air.
