The Effect of Motion on Time. I mentioned that time also changes with different frames of reference (motion). This is known as "time dilation". Time actually slows with motion but it only becomes apparent at speeds close to the speed of light. Similar to length contraction, if the speed reaches that of light, time slows to a stop. In Einstein's theory of relativity, time dilation describes a difference of elapsed time between two events, as measured by observers that are either moving relative to each other, or differently, depending on their proximity to a gravitational mass. Basically, it states that the faster we go, the more the time is affected. Length contraction is the phenomenon that a moving object's length is measured to be shorter than its proper length, which is the length as measured in the object's own rest frame. It is also known as Lorentz contraction or Lorentz–FitzGerald contraction (after Hendrik Lorentz and George Francis FitzGerald) and is usually only noticeable at a substantial fraction of the speed of light. In physics, time travel is closely linked to Einstein’s theory of relativity, which allows motion in space to actually alter the flow of time. This effect is known as time dilation and was one of the earliest predictions of relativity. This sort of time travel is completely allowed by the known laws of physics, but […] Special relativity indicates that, for an observer in an inertial frame of reference, a clock that is moving relative to him will be measured to tick slower than a clock that is at rest in his frame of reference.This case is sometimes called special relativistic time dilation. The faster the relative velocity, the greater the time dilation between one another, with the rate of time reaching The Effect of Motion on Time. I mentioned that time also changes with different frames of reference (motion). This is known as "time dilation". Time actually slows with motion but it only becomes apparent at speeds close to the speed of light. Similar to length contraction, if the speed reaches that of light, time slows to a stop. This can be confirmed by substituting a negative value in the standard time dilation equation for u^2. This results in a value greater than 1 occurring as the divisor, causing the numerator to 'shrink' in value, thus resulting in a 'time contraction' rather than time dilation.

## Time Dilation vs Length Contraction. Length contraction and time dilation are two important effects of the theory of relativity. These effects are extremely valuable in describing some of the most complicated phenomena encountered. This article will try to explain what length contraction and time dilation are, and the difference between them.

Length contraction is the phenomenon that a moving object's length is measured to be shorter than its proper length, which is the length as measured in the object's own rest frame.

### 22 Sep 2014 study of modern physics with special relativity. It is here that physics students first encounter the counterintuitive concepts of time dilation a

As stated in the third remark above, time dilation and length contraction are intimately related. We can't have one without the other. In the earth's frame, the muon's One of the peculiar aspects of Einstein's theory of special relativity is that the length of objects moving at relativistic speeds undergoes a contraction along the Einstein based his special theory of relativity on two postulates, the principle of They will overturn our classical presumptions about space and time. If it did not, then we could use the difference in the contraction of the light clock rod and Understand the effects of relativistic motion. Calculate the dilated time or contracted length due to movement close to light speed, for Higher Physics. As speeds increase towards the speed of light, the so-called relativistic effects of time dilation (clocks running slow) and length contraction (objects getting Tool to make calculations with time dilation. Time dilation is an effect of the special relativity which states that time is going slower if an object is moving.
