Concept explainers
People who ride in a bus all know they're moving through space. But you know that they're also moving through something else. What else are they moving through?
To explain: The quantity that peopleare moving through.
Answer to Problem 24A
They are moving through space and time.
Explanation of Solution
Introduction: In special theory of relativity, measurements are done on four dimensions- three axes in space and time.
Each object or person in motion changes its co-ordinates but while moving through one stationary reference frame or coordinate system. They also move in time because once they maneuver from one reference frame to another their respective time also shifts.
Conclusion: Thus, while moving in a bus, people are moving in one spatial frame to another while traveling in time.
