Simulate rigid body motion and collision with a few lines of code.
Create assets to bring your project to life.
Take advantage of Unity's existing game object primitives to build your scene.
Modify properties directly.
Create components to add physical properties to your game objects.
Play the game to see the interaction between objects.
