If you mean because someone at the equator is traveling faster than one at either pole, because their path/distance over a 24-hr time period is longer, that is correct, but hardly noticeable. In order for time dilation/length contraction/and mass increase effects to be important, speeds must be a significant fraction of light speed.
However, there is another means for time dilation, length contraction, and mass increase effects to occur: Gravity.
In short, the stronger the gravitational field, the greater the effects. GPS uses BOTH effects in its calculations in order to achieve such high degrees of accuracy. Interestingly, the greater of the effects is actually gravity, which of course is strongest nearer the surface than at high altitudes, as opposed to the high rate of speed of the GPS satellites, which has lesser time dilation, length contraction, and mass increase effects.
So, someone at the equator, due to the *outward* push of centrifugal force due to the rotation of the Earth, weighs LESS than someone of the same mass NOT on the equator. And so therefore has LESS time dilation, length contraction, and mass increase effects on them there than somewhere off the equator.
Things to consider with GPS satellites vs locations on the surface:
1) the high rate of speed of the satellites, vs stationary points on Earth
2) the stronger gravitational force at the surface vs that at the high altitude of the satellites.
In short, the satellites are experiencing time dilation, length contraction, and mass increase effects due to their high rate of speed, while the stationary positions at the Earth’s surface experiences effects due to the stronger gravitational force there. All in all, the gravity effects win out and are more important in the net calculations..
Yes i am referring to that difference and while minor.. the effect should be there...
Give rise to and interesting consent ive played with that time over an point of a given moving 3d object is different at any given point...I see time as similar to aerodynamic drag across the surface of an aircraft each point has different pressures... and adds the concepts you can “push off” time just like a wing can give lift in air from the pressure differential across its surface and a propeller can provide thrust from that same effect
