Chapter 15, Problem 10A

If you were traveling in a high-speed rocket ship, would clocks on board appear to you to be running slow? Defend your answer.

To determine

Whether the clocks on board appear to be running slow to the person traveling in a high speed rocket ship.

Explanation of Solution

Introduction:

The stretching of a time is known as time dilation. Einstein proposed thatdepending on the motion between observer and events being observed,time can be stretched.

If a person is travelling in the same ship with the clock on board, his clock will not slow, sinceboth are moving at same speed. There is no time dilation because the relative speed is zero. The person is seeing time inthe same frame of reference.

Conclusion:

As person and clock are in same frame of reference, clock does not appearsto slow.
