Question
1. Two identical atomic clocks initially standing next to each other are carefully synchronized. Then one of the clocks is placed on a jet plane which flies around the world at an essentially constant speed of 300 m/s, returning to the initial spot 37.1 hours later. The other clock remains at rest at the same initial spot. Assuming that the earth’s surface defines an inertial reference frame, and ignoring possible effects of gravity, which clock measures the shorter time interval between the synchronization and comparison events?
Explanation / Answer
The colck which is placed on jet will neasure shorter time interval because of time dilation.
