Simphy is a simulation software to create 2D and 3D simulations with easy drag and drop options. You can create different types of bodies inside its physics world with different parameters like restitution, friction, velocity etc.




The Powder Toy is a desktop version of the classic 'falling sand' physics sandbox game, it simulates air pressure and velocity as well as heat!.

Crayon Physics Deluxe is a 2D physics puzzle / sandbox game, in which you get to experience what it would be like if your drawings would be magically transformed into real physical objects. Solve puzzles with your artistic vision and creative use of physics.


iPhysics Sandbox is a simplistic physics sandbox (go figure). Depending on your personal setting configuration, its possible to get iPhysics engine to calculate every little attribute of every little object.




In Scribblenauts, you can write down any object you can think of and watch it come to life as you helped Maxwell on his quest.




FisicaLab (can be pronounced as PhysicsLab) is an educational application to solve physics problems. Its main objective is let the user to focus in physics concepts, leaving aside the mathematical details (FisicaLab take care of them).

A highly customisable virtual stressball and physics sandbox about mutilating ragdolls in various ways using an overwhelming amount of items and other tools.




It's way better plus there's add-ons and you can play with other people
