Collision2D is not a valid Unity "Magic" method so it is never called unless you handle it yourself. The one you are looking for is most likely OnCollisionEnter2D(Collision2D).

 using UnityEngine;
 using UnityEngine.SceneManagement;
 
 public class BallScript : MonoBehaviour
 {
     public Vector2 startForce;
     public Rigidbody2D rb;
 
     void Start()
     {
         rb.AddForce(startForce, ForceMode2D.Impulse);
     }
 
     // OnCollisionEnter2D is called when this collider2D/rigidbody2D has begun touching another rigidbody2D/collider2D (2D physics only)
     void OnCollisionEnter2D(Collision2D other)
     {
         if (other.gameObject.name == "wall_bottom")
             SceneManager.LoadScene("mainlevel");
     }
 }

Note that the SceneManager is the new way to manage scenes.
