physics engine
A physics engine is a computer software with which the laws of physics can be simulated. The term Physics Engine is generally used for programs with which physical laws and phenomena can be calculated and displayed. These include the laws of static and dynamic bodies, laws of fall, rotation, momentum and flow.
The Physics Engine runs on the Physics Processing Unit( PPU) and thus relieves the central processing unit of computationally intensive tasks. It supports users in simulating physical processes and displays extremely realistic material surfaces. The calculations themselves can be performed in real time or with the highest precision. The high-precision applications require extremely high computing power and are mainly used by researchers and scientists, whereas the real-time calculations are used in computer games.
