Physics Applets

Relativity

Link: Simulation

This applet was written by Patrick Leung as part of a School of Physical Sciences grant for enhancing the teaching of modern physics in first year laboratories. The applet shows a moving rod (or car) which is accelerated to apparently fit into a smaller box (or garage). The view can be from the car or garage frame of reference and an x-t diagram can be used to explain the apparent paradox.
