The EJS Energizer model explores the relationship between kinetic, potential, and total energy.  Users create a potential energy curve and obseve the resutling motion.

The Energizer model was created using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the jar file will run the program if Java is installed.
