Phys2D and JBox2D are 2D physics engines written in Java. Both are mainly intended to be used in games for increased realism. They simulate the physical interaction of geometric bodies like boxes, circles and simple polygons. Phys2D has been written by the author of the 2D games development library Slick. JBox2D is a Java-port of the C++ physics engine Box2D.

Since both offer very similar features, I took a closer look at them. Questions that interested me most were: How much performance do these physics engines cost? How do they compare to each other performance-wise? Which is easier to use?
