Physion is a free 2D physics simulation software that can be used to easily create a wide range of interactive physics simulations and educational experiments.
Physics teachers may find Physion useful as a virtual physics laboratory which they can use to demonstrate some basic physics concepts in the classroom.
Users can create various physical objects such as circles, polygons, and gears and joints (eg. springs, pulleys, and so forth) that obey the laws of physics. Scenarios can be created which may be either simple physics experiments or complex structures or mechanisms.
