In this post I will talk about one of the open source projects that caught my attention, because its main purpose is to provide libraries that allow us to simulate, taking into account the field of physics, the behavior of various objects and interactions that may exist between them, when, for example, there is a collision, or free fall acceleration due to a force, etc.. The project in question is called Box2D .
Box2D physics engine is open source, written primarily for games. As the name suggests, Box2D is purely a 2D engine. However, it is a project that has grown beyond its beginnings in which was limited to simulation, and can now handle convex polygons and other shapes available in the not too distant future.
Examples of features that provide the libraries Box2D, the next animation allows us to move various objects such as boxes, spheres, pendulums, among others, simply by using the mouse. You use the directional pad (<- y ->) for a change of scenery.

As you see, the demos of these libraries can be challenging to understand some concepts. It also can be used to create some animation or application related to the field of physics in 2D.
