It's not really a matter of "the most acceleration", the basic principle of the twin paradox is that if one twin doesn't accelerate at all between meetings while the other does at some point, the twin who accelerated will be younger. If both twins accelerate the problem will be more complicated and will depend on the particulars of when and where they accelerate as well as the magnitude of the acceleration they experience.ronirvol said:In the twin paradox, the twin that experiences the most acceleration does not age as much.
Suppose one watch doesn't accelerate at all between meetings with the other watch, which is placed on a centrifuge. In this case, just as in the twin paradox the watch that was accelerated on the centrifuge will show less time elapsed when it reunites with the watch that didn't accelerate--they will not remain synchronized.ronirvol said:If I synchronize two digital watches, then put one in a centrifuge for a long time, one watch will experience much more acceleration than the other. If they remain synchronized, why is the acceleration inside a centrifuge different from the acceleration if one watch had been in a space ship?
Acceleration is the rate of change of velocity over time. It is a vector quantity, meaning it has both magnitude and direction. In simpler terms, acceleration refers to how quickly an object's velocity is changing.
Acceleration is measured in units of length per time squared, such as meters per second squared (m/s^2) or feet per second squared (ft/s^2). It can be measured using devices such as accelerometers, which detect changes in velocity.
The twin paradox is a thought experiment that highlights the effects of time dilation and the concept of relativity. It involves a set of twins, where one twin travels at high speeds while the other remains on Earth. Due to the difference in their frames of reference, the traveling twin will experience less time, making them appear younger when they return.
In the twin paradox, the traveling twin must accelerate in order to change directions and return to Earth. This acceleration causes the traveling twin's frame of reference to differ from the stationary twin's, resulting in the time dilation effect.
While the twin paradox is a thought experiment, it is based on real scientific principles and has been observed in experiments with atomic clocks. However, the time difference between the twins in these experiments is extremely small and not noticeable to the naked eye. The twin paradox is more of a theoretical concept used to explain the effects of relativity.
