Prefab

• a prefabricated gameObject
• a gameObject we have configured the way we want, then saved as a prefab
• easily adding instances of the prefab to a scene in the editor
• easily adding instances of the prefab to a scene from a script(spawning)

Collision Detection

• Detecting collisions between gameObject
• if both game objects have 2D collider, the Physics 2D engine automatically does collision detection

Collision Resolution

• Doing something based on the fact that a collision has been detected
• 2D Physics materials for the game object colliders determine how the Physics 2D engine resolves the collision(Friction/Bounciness)
• Additional collision resolution by ourselves is possible
