Computer animation physics or game physics involves the introduction of the laws of physics into a simulation or game engine, particularly in 3D computer graphics, for the purpose of making the effects appear more real to the observer. Typically, simulation physics is only a close approximation to real physics, and computation is performed using discrete values.
There are several elements that form components of simulation physics:
- Physics engine is program code that is used to simulate Newtonian physics within the environment.
- Collision detection is used to solve the problem of determining when any two or more physical objects in the environment cross each other's path.

Famous quotes containing the words game and/or physics:
“I must save this government if possible. What I cannot do, of course I will not do; but it may as well be understood, once for all, that I shall not surrender this game leaving any available card unplayed.”
—Abraham Lincoln (1809–1865)
“He who is conversant with the supernal powers will not worship these inferior deities of the wind, waves, tide, and sunshine. But we would not disparage the importance of such calculations as we have described. They are truths in physics because they are true in ethics.”
—Henry David Thoreau (1817–1862)
