Objects have to follow the rules of physics to look realistic in a game. This lesson will try to answer your questions and give you some insight on an interesting application of physics. There is a mini-quiz at the end of this lesson. Areas of physics used in games Some of the areas of physics that require application and knowledge of the laws of physics are gravity, elasticity, light and sound. Since we see objects behaving according to the physics laws in our everyday lives, any deviation from those rules would make the game or the animation not look real.
Many equations used in physical science are statements of physics laws.
The equations are predictions of how an object should behave. Other equations are simple definitions. Of course, there are some exceptions that are used for dramatic effects, but in general we expect to see things behave as they should. Gravity All falling objects respond to the force of gravity according to the laws of physics. Falling objects accelerate according to certain equations.
