The PC version of iPhysics —— Phun 2D Physics Sandbox

What is Phun?

Phun is a small program written by Emil Ernerfeldt from Umeå University in Sweden for his master's thesis. It implements the physical laws of the real world, such as gravity, elasticity, friction, acceleration, etc.

This program can also be a very interesting game where you design levels to complete tasks. The scenes you design can be saved and made available online for others to use. For learning physics, this program can also be used as a teaching aid, capable of intuitively simulating the effects of real-world physical motion.
