How Games Simulate Real World Motion
Game physics is the system that simulates real-world laws like gravity, motion, collisions, and forces inside a game engine.
Gravity 🌍 → pulls objects down Force 💪 → pushes objects Velocity 🚀 → speed + direction Acceleration ⚡ → change in velocity
Box Collider 📦 → simple shape collision Sphere Collider ⚪ → round objects Mesh Collider 🧩 → complex shapes
Adds physics behavior to objects: - Gravity - Mass - Forces - Real movement
F = m × a Force = mass × acceleration
Jumping → gravity + velocity Shooting → projectile motion Driving → friction + acceleration Falling objects → gravity simulation
Rigid Body Physics 🧱 → solid objects Soft Body Physics 🧸 → cloth, jelly Fluid Physics 🌊 → water, smoke
Unity → PhysX engine ⚙️ Unreal → Chaos Physics Engine ⚡ Both handle: - Collisions - Gravity - Simulation
