One problem with students starting to work with Unity is to understand when colliders work and when they do not work. This very simple demonstration shows how Physics::AddForce(), CharacterController:: SimpleMove() and Translate.Transform() behaves with colliders. Moving a GameObject using Physics and CharacterController based methods interacts with collisions whereas Transform::Translate() does not as seen in the video. Moreover, Translate does not work with MonoBehavior::OnTriggerEnter().

Physics::AddForce():

public class PhysicMove : MonoBehaviour {

	void Start () {
		rigidbody.AddForce (new Vector3 (100, 0, 0));
	}
}

CharacterController::SimpleMove()

public class Move : MonoBehaviour {

	public float speed;

	private CharacterController controller;

	void Start () {
		controller = GetComponent ();
	}
	
	void Update () {
		controller.SimpleMove (new Vector3 (1, 0, 0) * Time.deltaTime * speed);
	}
}

Transform::Translate()

public class MoveTranslate : MonoBehaviour {

	public float speed;

	void Start () {
		enabled = false;
	}

	void Update () {
		transform.Translate (new Vector3 (1, 0, 0) * Time.deltaTime * speed);
	}
}
