Motion and Speed
... • Most of the time objects do not travel at a constant speed – You probably do not walk at one constant speed on the way to class • This is why when we talk about how fast an object is moving we are usually talking about its average speed. • If we are talking about an object’s speed at a particular ...

... Now let us examine this measurement from the point of view of the observer on the Earth. From her point of view, the length of spaceship A is smaller than L0 . And the moving stopwatches slow down compared to watches left on the Earth, so the time measured by the watches on the Earth is longer than ...

Time dilation
In the theory of relativity, time dilation is a difference of elapsed time between two events as measured by observers either moving relative to each other or differently situated from a gravitational mass or masses.An accurate clock at rest with respect to one observer may be measured to tick at a different rate when compared to a second observer's own equally accurate clocks. This effect arises neither from technical aspects of the clocks nor from the fact that signals need time to propagate, but from the nature of spacetime itself.
