If there were no drag, then this, of course, would be a parabola, and the horizontal velocity would always be the same. 如果没有阻力，这应该是个抛物线，水平速度，也应该一样。 - 2
Because of the resistive forces, because of the drag by the liquid, the object is going to get a velocity in this direction, so there's going to be a component of the resistive force opposing it. 因为阻力，因为液体中的阻力，物体的速度，是朝这个方向，所以会有，一个相反的阻力。 - 3
It appears, however, that the "drag coefficient", CD, also depends on the velocity of the ball.
