Learning Objectives By the end of this section, you will be able to: Figure 28.13 The total velocity of a kayak, like this one on the Deerfield River in Massachusetts, is its velocity relative to the water as well as the water’s…
Learning Objectives By the end of this section, you will be able to: Figure 28.9 People might describe distances differently, but at relativistic speeds, the distances really are different. (credit: Corey Leopold, Flickr) Have you ever driven on a road that seems…
Learning Objectives By the end of this section, you will be able to: Figure 28.4 Elapsed time for a foot race is the same for all observers, but at relativistic speeds, elapsed time depends on the relative motion of the observer and…
Learning Objectives By the end of this section, you will be able to: Figure 28.3 Special relativity resembles trigonometry in that both are reliable because they are based on postulates that flow one from another in a logical way. (credit: Jon Oakley,…
Figure 28.1 Special relativity has implications and applications ranging from space travel and our understanding of time to everyday technologies such as Global Positioning Systems. In order to be effective, GPS, whether it is a part of a mobile phone or a…
