Does motion affect the rate of a clock as measured by an observer moving with it?

1. a) If the observer moves with the clock, the movement does not affect the speed of the clock. According to the relativistic law of addition of velocities, there is no speed greater than the speed of light.

What does the twin paradox tell us about time?

In this supposed paradox, one of two twins travels at near the speed of light to a distant star and returns to the earth. The paradox lies in the question “Why is the traveling brother younger?” Special relativity tells us that an observed clock, traveling at a high speed past an observer, appears to run more slowly.

What is the twin paradox in physics?

In physics, the twin paradox is a thought experiment in special relativity involving identical twins, one of whom makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has aged more. In both views there is no symmetry between the spacetime paths of the twins.

Why is simultaneity relative?

theory of relativity implies that simultaneity is relative to a frame of axes. If one frame of axes is moving relative to another, then events that are simultaneous relative to the first are not simultaneous relative to the second, and vice versa.

Does the twin paradox exist?

Q: Does the twin paradox exist? The twin paradox is real as the traveling twin will see the Earth clock moving as slowly as the twin on the Earth. Yes, it is real but shouldn’t really be called a paradox. Q: How is special relativity different from general relativity?

At what speed does a clock move if it runs at a rate which is one half the rate of a clock at rest?

so sqrt(0.75) = v / c = ~ 0.866 which means the velocity is 86.6\% of the speed of light.

Has the Twin Paradox been tested?

The twin paradox is real as the traveling twin will see the Earth clock moving as slowly as the twin on the Earth. Yes, it is real but shouldn’t really be called a paradox.

Why do clocks tick slower in special relativity?

Special relativity indicates that, for an observer in an inertial frame of reference, a clock that is moving relative to him will be measured to tick slower than a clock that is at rest in his frame of reference. This case is sometimes called special relativistic time dilation.

Can two objects move at the same speed but measure different times?

If they are moving at constant velocity relative to each other, however, they measure different times. As an example, let’s say one observer stays on the Earth, and the other goes off in a spaceship to a planet 9.5 light years away.

What happens when time slows down for an object?

Common sense would dictate that, if the passage of time has slowed for a moving object, said object would observe the external world’s time to be correspondingly sped up. Counterintuitively, special relativity predicts the opposite.

Why is the clock on a space ship running so slow?

The one thing that might puzzle you is this: everything is relative, so a person on the Earth sees the clock on the spaceship running slow. Similarly, the person on the Earth is moving at 0.95c relative to the observer on the spaceship, so the observer on the ship sees their own clock behaving perfectly and the clock on the Earth moving slow.
