what causes time differrences in time perception in relativity. acc or vel? or simply motion.?

Question

I want to know if acceleration is the key factor, as any other ordinary motion is all relevant anyway and hence irrelevant.

ofcourse 'RELEVANT' should be 'RELATIVE'

Answer 1

The key factor here is the Velocity, the more the velocity the more the time relativity. The acceleration per say doesn't have any role to play in the relativity but contributes in the form of time dilation i.e. at higher the acceleration the higher the passage of time. Thus, in the relativity Velocity is predominant and acceleration plays the secondary role.

Answer 2

All motion appears to be relevant, but the fast the motion the more pronunced the effect.

We, on the Earth, are travelling at some 500,000 MPH or more. If we were to step of and slow to a hault in space we'd probably die of old age before we were motionless.

Answer 3

Relative motion is what creates a time distortion from each other perspective. In other words, your absolute time will be directly proportional to your relative speed.

The faster you go (relatively speaking), the slower your clock will tick as seen by another subject that is moving slower than you. To your own eyes, is their clock the one that will tick faster.

Acceleration has nothing to do with it.

Answer 4

Velocity.

Answer 5

Both. Also gravity.

Answer 6

It is velocity ...
