Game physics refers to the simulation of physical laws in video games, allowing objects to move and interact in a realistic manner. This includes how characters jump, how objects fall, and how collisions occur. By using mathematical models, developers create environments that mimic real-world physics, enhancing the player's experience. Incorporating game physics helps to create immersive gameplay, making actions feel believable. For example, when a player throws a grenade in a game, the trajectory and explosion effects are calculated based on physics principles. This realism contributes to the overall enjoyment and engagement of players in the virtual world.
