Pymunk is a Pythonic 2D rigid body physics library built on top of Munk2D (a fork of Chipmunk2D). It provides easy-to-use physics simulation for games, demos, and scientific simulations from Python.

Use cases

• add 2d physics to a python game
• simulate rigid bodies with gravity in python
• collision detection between shapes in pygame
• run a physics simulation for a demo or research paper
• build a breakout or platformer game with python
• simulate physics for a self-driving car simulation

When to choose

• you need 2D rigid body physics in a Python project
• you use pygame, pyglet, or kivy and want physics integration
• you want a mature, MIT-licensed physics library with 15+ years of development
• you need wheels for desktop, mobile, or web (pyodide) targets

When to avoid

• you need 3D physics simulation
• you need a physics engine in a non-Python language
• you require thread-safe physics stepping in free-threaded Python
