Time dilation for dummies. Time dilation in the theory of special relativity the slowing down of a clock as determined by an observer who is in relative motion with respect to that clock. In special relativity an observer in inertial ie nonaccelerating motion has a well-defined means of determining which events occur simultaneously with a given event. Time dilation is the idea that as you move through space time itself is measured differently for the moving object than the unmoving object.

For motion that is near the speed of light this effect is noticeable and allows a way to travel into the future faster than we normally do. Time dilation helps explain how the speed of light doesnt change with perspective. The speed of light is abbreviated by the letter c and its approximately 300000 kilometers per second kps -.

Time dilation is the lengthening of the time interval between two events for an observer in an inertial frame that is moving with respect to the rest frame of the events in which the events occur at the same location. We can see that is the velocity is small compared to the speed of light the quantity v 2 c 2 approaches 0 and the equation simplifies t 0. T t 0 1 which is simply t.

So at relatively slow speeds our everyday speeds time dilation is not a factor and Newtons Laws are still applicable. One of the strangest consequences of time dilation is the so-called twin paradox. In this paradox one identical twin is sent at very high speed out into space.

Because he or she is travelling at a very high speed all the clocks on board the rocket including the body clock of the twin slow down in accordance with the principle that moving clocks run slow. In order to attempt to prove this theory of time dilation two very accurate atomic clocks were synchronized and one was taken on a high-speed trip on an airplane. When the plane returned the clock that took the plane ride was slower by exactly the amount Einsteins equations predicted.

This phenomenon is called gravitational time dilation. This is what the wiki page says about it. - Gravitational time dilation is an actual difference of elapsed time between two events as measured by observers differently situated from gravitational masses in regions of different gravitational potential.

The fact that the speed of light is the same in all reference frames has the consequence that moving clocks run slow. This means that if two events occur at the same place such as the ticks of a clock a moving observer will measure the time between the events to be longer. One of the earliest and most well-known thought experiments to feature time dilation is the famous Twin Paradox which demonstrates the curious effects of time dilation at its most extreme.

Time dilation becomes most apparent when one of the objects is moving at nearly the speed of light but it manifests at even slower speeds. In physics and relativity time dilation is the difference in the elapsed time as measured by two clocks. It is either due to a relative velocity between them kinetic time dilation from special relativity or to a difference in gravitational potential between their locations gravitational time dilation from general relativityWhen unspecified time dilation usually refers to the.

In Einsteins 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. Gravitational time dilation is a physics concept about changes in the passage of time caused by general relativity.

A clock in outer space moves more quickly than a clock on Earth. Heavy things like planets create a gravitational field that slows down time nearby. Even the functions of your cells and your body are governed by the interactions of particles and thus experience the effects of special relativity such as time dilation which well get to.

Now relativistically every interaction happens at a finite speed under the speed of light c which actually results in quite weird consequences when things start moving at different velocities. For interest you may want to paste the time dilation formula below into Excel. Its the standard time dilation formula and in this case should give a result of 1 but instead gives 0999949999.

SQRT 1- 11 100100 Here are some examples to try. Apart from the Sun the nearest stars to us form the Alpha Centauri system. An Example of Time Dilation A spaceship is flying a distance of 5 light hoursfor example from Earth to the dwarf planet Pluto.

The speed can be regulated with the upper buttons. Of the system in which Earth and Pluto are motionless. This is the currently selected item.

Video transcript - Voiceover So lets revisit a scenario that we have seen in several videos especially the last video where we tried to find this neutral frame of reference. Lets say were in spaceship A. We are in an inertial frame of reference.
