Time dilation also for accelarated motion?

[Rhian]

Is the time dilation effect also valid for accelerated Motion or only for v=const, a=0 ?

Thanks.

Thanks.

Properly calculated, time dilation is valid for accelerated observers.

Yes, the time dilation effect is also valid for accelerated motion. It is a fundamental principle of the theory of relativity that time is not absolute and can vary depending on the relative speed and acceleration of an object. This means that in the presence of acceleration, time will pass differently for different observers.

In fact, the famous equation for time dilation, t' = t/sqrt(1-v^2/c^2), takes into account both velocity and acceleration. This means that even if an object is accelerating, its time will still be dilated relative to a stationary observer.

Additionally, the concept of gravitational time dilation, which is the effect of gravity on the passage of time, also applies to accelerated motion. This is because acceleration and gravity are equivalent according to the principle of equivalence in general relativity.

So, to answer your question, the time dilation effect is valid for both constant velocity and accelerated motion.
