Physics in Games – Gravity, Collision Detection & Rigid Bodies Explained

Physics helps games feel realistic and believable. It controls how objects move, fall, collide, and react. Game engines simulate physics in real time to create smooth and engaging gameplay experiences.

Gravity is the force that pulls objects downward toward the ground. In games, gravity affects jumping, falling, and object drops. Some games use realistic gravity, while others exaggerate it for fun gameplay.

Collision detection checks when two objects touch or overlap. It prevents characters from passing through walls. It is also used for hits, damage, scoring, and interactions in games.

Rigid bodies are objects that do not change shape. They respond to forces like gravity and collisions. Common examples include boxes, cars, balls, and walls.

A physics engine combines gravity, collision detection, and rigid body responses. Together, these systems simulate how objects behave in a game world and help create believable gameplay.
