It's the basic physics that the air is thinner and the resistance to any projectile is less so the flight path of the ball will be different at high altitude.
基本物理学理论上，空气越稀薄情况下，任何物体的耐性都会减少，因此球路也会因海拔高度不同而有所变化。
As mentioned above, in the professional forehand, the rotation of the racquet head into the path of the ball is delayed until just before the strike stage.
如上所提到的，在职业球手的正手拍，网球拍头的旋转进入球的路径内的时间点，被延迟到就刚刚在打击阶段之前。
She could have extended the frame even more through the path of the ball, but I think the fact that she didn't is probably because she's added topspin to this shot.
她可以增加自己的攻击线路通过球的线路，但是我想她可能没有这样做，因为她给这个球增加了上旋。
Suppose this is the flight path of the ball. I retreat to a position far behind the table. The ball has just fallen. I start with the paddle well above and behind the ball.
假设这是球的飞行路线，我退到离球台很远的地方， 球正好落下来，我向球的后上方引拍。
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。
Ironically, that lack of spin on the ball causes its path to curve because of aerodynamics.
具有讽刺意味的是，这种失去旋转的球，由于受到空气动力学方面的影响，会使球从正常的轨迹中发生偏离。
While the Teamgeist ball was great for strikers, many goal keepers complained that the ball's aerodynamics created a lack of rotation in the air, making its path at times erratic, like a knuckleball.
由于“团队之星”独特的空气动力学设计，导致飞行的球在空中缺乏旋转，这种设计遭到了很多门将的诟病，他们认为这样的球飞行路径过于飘忽，难以判断。
United 2-0 Spurs (Anderson 76') Great move, concluding with a wonderful one-two in which Welbeck backheels the ball back into the path of Anderson, who slots into the net from 12 yards.
0热刺（安德森第76分钟）漂亮的跑位，在经过一次漂亮的撞墙配合后，维尔贝克脚后跟一磕传给中路的安德森，安德森12码处一蹴而就。
The change in path of the visible ball would tell us about the presence of the invisible ball.
看得见的球的运动轨迹的改变，就可能告诉我们：看不见的球是存在的。
This met hod was applied to the volleyball robot, and it realized hitting action of the ball along its path anywhere within the robot workspace.
将该方法应用于确定排球机器人击球点，实现了在排球机器人工作空间内的球运动路径上任意位置回球。
A light object, like a tennis ball, on the edge of the trampoline will follow a curved path toward the bowling ball - like a planet orbiting the sun.
而蹦床边缘的轻物体，比如网球，将沿着曲面移向保龄球-就像行星围绕着太阳运行。
The swerving of a ball from a straight path of flight, as in baseball or cricket.
棒球胜于板球的一大优点在于完的快。
