Section 2.6: Exploring Worldlines by Matching

Please wait for the animation to completely load.

Use the mouse to drag the red ball to change its position. The goal of this Exploration is to match the worldlines shown in the animation (position is given in meters and time is given in the time required for light to travel 1 meter or 3.33 × 10−9 seconds). There is some smoothing of the data sent to the graph.  Restart.  Try to match each worldline, then answer the following questions:

  1. Which of the graphs was the easiest to match and which one was the hardest to match?
  2. Why?

When you get a good looking graph, right-click on it to clone the graph and resize it for a better view.
