为了描述物体运动速度快慢这一特征,引入了加速度(acceleration)的概念:加速度是速度的变化量与发生这一切变化所用时间的比值,通常用a表示。
目录 中文名称: 加速运动 英文名称: accelerated motion 简介 编辑本段 回目录 方向单一(设定一个正方向),速度大小可改变【速度在(0,∞)这个范围内】,速度递增的话是加速运动。反之减速运动。 加

电影可以扭曲时间,减慢或加速运动,展示淡入淡出场景的演员,等等。
Movies can distort time, slow movement down, or speed it up, show actors fading in and out of scenes, etc.
虽然还没有发现一种速度与光一样或比光还快的物质,但科学实验已经证实,加速运动会延长旅行者的时间。
Although no form of matter yet discovered, moves as fast as or faster than light, scientific experiments has already confirmed that accelerated motion causes a traveler's time to be stretched.

The answer is that simply knowing the particle has an acceleration is not enough to tell you where the particle will be.
答案是这样的,仅仅知道质点的加速度,是不足以告诉你它接下来的运动的
In other words, you don't have to be moving actually in a circle to have the acceleration.
也就是说,你不必真的在一个圆上运动以获得相应的加速度
This particle is constantly changing its direction, but it therefore has an acceleration and the acceleration, we have shown here, is pointing towards the center.
这个质点恒定地改变它的运动方向,因此它具有加速度,而且这个加速度,我们前面也讲过了,指向圆心
