Is velocity affected by time?

Originally Answered: Why does velocity affect time? It does not affect time, it just affects how you travel in time. See it this way: we constantly move at the speed of light in spacetime (this is no analogy, it is completely true when using the relativistic definition of velocity called four-velocity).

How the theory of relativity affects time?

In the Special Theory of Relativity, Einstein determined that time is relative—in other words, the rate at which time passes depends on your frame of reference. The faster a clock moves, the slower time passes according to someone in a different frame of reference.

What causes velocity time dilation?

Time dilation doesn’t just occur because of relative motion, it can also occur because of gravity. Einstein’s theory of relativity says that gravity is a property of the warping of space and time. So when you have a mass like Earth, it actually warps space and time.

Is time dilation based on velocity or acceleration?

In the inertial reference frames of special relativity, time dilation is dependent on speed, and not at all on acceleration.

How does speed and gravity affect time?

The stronger the gravity, the more spacetime curves, and the slower time itself proceeds. Time itself is slowing down and speeding up because of the relativistic way in which mass warps space and time. Earth’s mass warps space and time so that time actually runs slower the closer you are to earth’s surface.

How does velocity affect time dilation?

The faster the relative velocity, the greater the time dilation between one another, with time slowing to a stop as one approaches the speed of light (299,792,458 m/s). For sufficiently high speeds, the effect is dramatic.

How is the notion of time affected by velocity?

Thus, the flashes of light will strike the ends of the traincar at different times. So, it is clear that relatively moving observers ascribe different time intervals between the same pair of events as simultaneity is relative. This is how notion of time is affected by velocity.

Is relative velocity time dilation symmetric without contradiction?

But, we find that clocks synchronized in one object’s frame are not synchronized in the other relatively moving object’s frame. Thus, the relative velocity time dilation is symmetric without contradiction. We can’t say that one or the other clock is absolutelyrunning slower.

What is the difference between time dilation and general relativity?

In Special Relativity the time dilation is just a matter of convention in the time measurement between moving frames. In General Relativity the time dilation is a physical phenomenon which involves a force field (either gravity or acceleration or wathever) that actually slows down the particles of a system.

Is it possible to have velocity without acceleration?

You can’t have velocity without acceleration. It’s the inertial force with acceleration that breaks the symmetry. My understanding is that the asymmetry is where the inertial frame changes. Measuring time between two objects with different inertial frames is where you have time dilation.
