Of course, in reality, the baseball player knows better They give effect to the ball, they deal with air drag they spin the ball, and then these equations are not valid.
当然，还是棒球选手更了解现实情况,他们用特殊的抛球方式减小空气阻力,他们使球在飞行时带自转，这些公式就无法应用了。
Drag is the force of air resistance pushing against a ball's motion and slowing it down, while lift is a force causing a ball to swerve off a straight path.
拉力是一种物体在空气中所受到的阻力，它能产生与球运行方向相反的作用力，减缓球的运行速度，而升力则是一种能使物体偏离直线运行轨迹的力。
This substantially increased the drag on the ball, which made it slow down even more.
这大幅增加了球的阻力，使它减速更甚。
The flow of air over the surface of the ball was turbulent, which gave the ball a relatively low amount of drag.
球的表面流动的空气形成湍流，这使得球的阻力相对较低。
It appears, however, that the "drag coefficient", CD, also depends on the velocity of the ball.
然而，阻力系数CD，也取决于球的速度。
"You have your wits scared out of you, drag your butt out of a flaming ball of wreckage and you can't even get a vodka-tonic," he wrote.
“你吓得魂不附体，正从烧得像球一样的残骸中把自己的”大部分“给拽出来，你居然得不到一杯伏特加酒的安慰，”他写道。
To establish a link, click the blue ball on the edge of the source component, hold down the mouse and drag the link to the target component.
要想建立一个链接，请单击源组件边缘上的蓝色球，按住鼠标并将链接拖动到目标组件。
If you kick the ball hard enough for the airflow over the surface to become turbulent, then the drag force remains small and the ball will really fly.
如果你踢球的力量足够大，使得球表面的气流形成湍流，则阻力会很小，你很可能踢成高射炮。
The drag force acts in the opposite direction to the path of the ball.
阻力方向与球的运行方向相反。
There is air drag on that tennis ball.
网球受到空气阻力。
The forces on a spinning ball that is flying through the air are generally divided into two types: a lift force and a drag force.
空气中运行的旋转球的受力通常分为两种：升力和阻力。
Operational Guidelines for School Official Cites Use: Drag the mouse click ball control, shooting.
操作指南：鼠标左键拖动球控制力度、击。
Very Simple ball drag and throw engine. Could be used for multiple games. Enjoy.
很简单的拖动和扔球源码。可用于多种游戏。
The magnitude of pressure has nothing to do with the direction of the rotation and the drag coefficient is larger than that of a non-rotation golf ball.
并发现带有旋转效应的凹坑高尔夫球受到的阻力系数增大；
Yes, I'm going to the party tonight, but I'll have to drag along my ball and chain.
是呀，我要参加今天的社交晚会，但是我必须带著我家的母老虎。
The Aero-Box Vari Frame reduces wind drag compared with a standard air-flow pattern, maximizing the power of the swing and the transfer of energy to the ball.
拍框上部可以减少挥拍空气阻力，拍框下部可以增加控球能力，让球拍攻防兼备。
