Com Padre Digital Library: Open Source Physics: Simultaneity Spacetime Diagram
Manipulate variables in order to observe the effects of relative motion on events such as an explosion and the time at which its light signal reaches a destination.
Stanford University
Stanford University: Conventionality of Simultaneity
This site from Stanford University is on the topic of simultaneity in relativity.

Com Padre Digital Library: Open Source Physics: Ejs Simultaneity Model
A model for examining the simultaneity of two events where the relative velocity and the wave source, either light or sound, can be manipulated.
American Association of Physics Teachers
Com Padre Digital Library: Open Source Physics: Relativity Metric Program
Graphical visualization of how the relative motion of two events affects their spatial and temporal separation in special relativity.

Exploratorium: The Doppler Effect
Visit this page to see an animation demonstrating the Doppler Effect. How do sound waves and electromagnetic waves behave similarly with this effect?
Physics Aviary
Physics Aviary: River Crossing Lab
This lab is designed to have students look at relative motion in a two dimensional environment. Students are to launch toy boats across a waterway and look at the motion relative to the shore or the motion relative to the water.

Com Padre Digital Library: Open Source Physics: Simultaneous Events Program
Simulation showing how relative motion affects event order in special relativity. Manipulate the relative speed of two simultaneous events and observe the results.
American Museum of Natural History
American Museum of Natural History: O Logy: It's All Relative
Learn about the 4th dimensions and the theory of relativity.There is no absolute, or "same," time and space. This means time and space are different for everyone! How you experience events in time and space depends on two important...
