相对论运动物体的视速度和视加速度

The Apparent Velocity and Acceleration of Relativistically Moving Objects

Austen Berlet, Dennis G. C. McKeon, Farrukh Chishtie, Martin Houde

摘要:

虽然狭义相对论将粒子的实际速度限制为光速$c$,但观察到的速度不需要与实际速度相同,因为观察者只知道粒子在过去发出检测信号时的位置。我们在两种情况下考虑粒子的视速度和视加速度,一种是当粒子以恒定速度运动时,另一种是当粒子以恒定加速度运动时。我们的结果的一个奇怪特征是,在这两种情况下,如果粒子的实际速度接近$c$,那么当它向观察者移动时,表观速度接近无穷大,而当它远离观察者时,表观速度接近无穷大,而当它远离观察者时,表观速度接近无穷大。$c/2$。

英文摘要:

Although special relativity limits the actual velocity of a particle to $c$, the velocity of light, the observed velocity need not be the same as the actual velocity as the observer is only aware of the position of a particle at the time in the past when it emits the detected signal. We consider the apparent speed and acceleration of a particle in two cases, one when the particle is moving with a constant speed and the other when it is moving with a constant acceleration. One curious feature of our results is that in both cases, if the actual velocity of the particle approaches $c$, then the apparent velocity approaches infinity when it is moving toward the observer and $c/2$ when it is moving away from the observer.
