A physics simulation updates a system according to rules for motion, gravity, collision, friction, constraints, fluids, or other physical effects. Games often use simplified real-time physics that feels convincing rather than reproducing every detail of the physical world.
AI-generated software can configure or code a simulation quickly, but the result still needs stability and edge-case testing. Incorrect units, collision shapes, time steps, constraints, or extreme values can create unrealistic or broken behavior.

Physics simulation makes digital objects move and interact using mathematical rules. It helps a game or model imitate effects such as gravity, bouncing, friction, and collisions.
For example, a kart game can use a simulation to decide how the vehicle accelerates, turns, lands after a jump, and reacts when it hits a wall. Testers check that the behavior stays stable.
