【Special Relativity】

For a clock moving at the velocity v = ˆxv in S, how much change in time does
it read over a lapse of time of "t in S? For an observer at rest in S, when he/she sees
the face of the clock, how fast is the clock ticking in comparison with his/her own
watch? Consider separately the two possibilities: (a) the clock is moving towards the
observer, and (b) the clock is moving away from the observer.

Answer #1

As we know in general that the time dilation is given by

So we have the two cases

1. When moving toward the S then

v is (-v) so we get

Now for the other case

2. Moving away from the S then

v will be now +v so

it will be given by

So we get that the time will remain same for the observer in both of the cases . And that is

Mass of a Moving Particle The mass m of a particle moving at a velocity v is related to its rest mass m0 by the equation m = m0 1 − v2 c2 where c (2.98 ✕ 108 m/s) is the speed of light. Suppose an electron of rest mass 9.11 ✕ 10−31 kg is being accelerated in a particle accelerator. When its velocity is 2.84 ✕ 108 m/s and its acceleration is 2.49 ✕ 105 m/s2, how fast is...

Sam is on a spaceship that travels from Earth to Proxima Centauri at 70% the speed of light, or 0.7c, relative to Earth. Erma is an observer on Earth. From Sam's perspective, 1.35 x 108 seconds passed between when the Earth was near him and when Proxima Centauri is near him First we consider velocity and time: How fast in m/s is Sam moving as measured in the rest frame of the rocket? How fast in m/s is Erma moving...
