This AAPT-ComPADRE interactive textbook was developed to provide easy access to Open Source Physics (OSP) simulations that respond to the acceleration and orientation when run on a mobile device.  The simulations were developed by Wolfgang Christian using the Easy Java/JavaScript modeling and authoring tool created by Francisco Esquembre.  Colleen Countryman is class-testing these simulations at North Carolina State University.
