Clock Synchronization and Simultaneity The synchronization of clocks first came up when we carefully examined the process of measuring when events happen in an inertial coordinate system. At that stage, we emphasized that it is an essential step in setting up such coordinate systems. Last time, as we discussed clock-transport synchronization, we began to discuss the relationship between the measurements and representations of when and where events happen that observers make when using different inertial coordinate systems that are in motion relative to each other. This is an important topic in relativity. We initially focused on clock-transport synchronization in a Universe governed by pre-relativistic Newtonian physics to begin developing the relationship between inertial coordinate systems in relative motion in a familiar context. e can compare and contrast that relationship with the one in a special We can compare and contrast that relationship with the one in a special relativistic Universe to help us understand Einstein’s relativity. Today, we wrap up our analysis of Newtonian relativity.

Question 1. t This spacetime diagram depicts events occuring in a Newtonian Universe. A clock moving at sec constant velocity passes you at event 0. Both it and your identical clock tick at that event. Event 1 is the next tick of your clock. worldline of your master clock vent 1 event A vent B Which event corresponds to the next tick of the moving clock? event 1 event B event C A) B) C) worldline of a oving clock D) event 1 x moving clock event 0 light-seconds

Newtonian Relativity and the Galilean Transformation Equations In section R1.6 the text discusses the relationship between the time and space coordinates measured and used to represent events that occur in two inertial coordinate systems, the Home and Other frames. Because these t ec frames are in standard orientation the Other frame moves at constant speed V in the x direction relative to the other frame.
