Dilation Disk Rotating Rotating disk Time Time dilation

In summary, the relative time difference between two observers confuses me (i.e. that a high speed observer, and a stationary observer will each perceive the other's clock to run slow.).

Is this frame rotating or not? You can pick either answer: both are valid. But you have to be clear about which you are using. And then you have to realize that answers to other questions can depend on which you pick. If you pick the non-rotating frame (which is often called an "Earth-Centered Inertial" frame in the literature), then yes, the satellite is moving relative to this frame. But if you pick the rotating frame (which is often called "Earth-Centered Earth-Fixed"), the satellite is not moving. So whether the satellite is moving depends on which one you pick: there is no unique answer to the question.

1. What is time dilation of a rotating disk?

Time dilation of a rotating disk is a phenomenon in which time appears to move slower for an observer on the edge of a rotating disk compared to an observer at the center of the disk. This is due to the effects of gravity and the rotation of the disk.

2. How does time dilation on a rotating disk occur?

Time dilation on a rotating disk occurs because the speed of rotation causes a difference in the strength of gravity experienced by an observer at the center of the disk compared to an observer at the edge of the disk. This difference in gravity affects the perception of time.

3. How does the speed of rotation affect time dilation on a rotating disk?

The faster the rotation of the disk, the greater the difference in gravity between the center and edge of the disk, resulting in a greater time dilation effect. This means that time will appear to move slower for an observer on a faster rotating disk compared to an observer on a slower rotating disk.

4. Is time dilation on a rotating disk a real phenomenon?

Yes, time dilation on a rotating disk is a real phenomenon that has been observed and confirmed through experiments and mathematical calculations. It is a consequence of the theory of relativity and has been extensively studied and documented by scientists.

5. Can time dilation on a rotating disk be reversed?

No, time dilation on a rotating disk cannot be reversed. It is a fundamental aspect of the theory of relativity and is a consequence of the laws of physics. However, the effects of time dilation can be counteracted through other means, such as by using a gravitational time dilation compensator.
