if time travels slower when you are moving??

Question

Does that mean the clock in my car would be fractionally slower then the clock at home ,if they both kept perfect time?

Answer 1

Yes, in fact, if you drove 70 miles per hour, 24 hours a day 365 days a year, the time difference would be .00000003168895541034 seconds!

What a wonderful way to save time. . .

Addition:

I started calculating this before others had answered, but now I must comment on their answers.

First, the movement of the earth and sun are irrelevant, unless you plan on driving your car into space, those velocities would be the same for both the house and the car.

Second, direction does not matter, netiher does magnatic forces. Gravity does matter, however, in my calculation, I assumed gravity is constant (yes, it does vary a little over the surface of the earth, but to throw all that into the equation I would need a lot more information and a lot more time and a heck of a lot more motivation).

Answer 2

Fractionally slower OR fractionally faster - when they have oprbited the Earth, the cronometers either lose OR gain an extremely tiny amount depdning on which direction they are travelling.

Now this is all a bit strange - as it would suggest that there is more at play here than simple speed (cannot be veolcity as they circled globe).

Why would time be altered by the *direction* of travel - was this anything to do with the poles? Does this suggest that magentic fields may have a contribution to make - indeed a most significant one if it skews a losing clock to a gaining clock?

Note however that the clock in your car could be about the same (travelling in one direction and then the OtHER direction thus cancelling the effect out).

Alas this answer invites even more questions!

Answer 3

Yes...although the speed difference between your clock in the car...and home would be very, very insignificant. You would need two clocks with incredible accuracies to even measure the difference. This effect (predicted by Einstein) was actually proved in the early days of NASA. An clock placed within a rocket and orbited around the Earth...lost time relative to an identical clock which remained on the ground.

Answer 4

Yes, but only by the very tiniest amount.

And, don't forget, that time only moves slower for you when you're travelling from the point of view of an observer. Within your own frame of reference, time would be ticking on at the same rate regardless of your speed.

Answer 5

Yes, but to notice an effect you'd have to travel very fast or your clock would have to measure thousand trillionths of a second.

Answer 6

According to relativistic science, yes. It seems that things that have been around for the same amount of time are not exactly the same age.

Thank you for reminding me !!

Answer 7

interesting, everything is in motion, the earth rotating,and orbiting the sun and then the movement of the solar system, with the movement of the universe... I kinda wonder what is standard time?

Answer 8

According to Einstein's relativity, but I am not sure he was correct on that bit.

Answer 9

A persons Time is `Subjective`i.e. your emotional state.
