Shooting golf ball

[plavokablo]

Hi,
I am trying to make mini golf game. So far I’ve created scenes and ball. Also i made script for rotating camera. I am stuck on shooting ball script. This is my script for shooting ball.
using UnityEngine;

public class Pucanje : MonoBehaviour
{
    public float thrust = 1000;    
    private GameObject ball;

    void Start()
    {
        
        ball = GameObject.Find("Sphere");
    }

    void Update()
    {
        if (Input.GetMouseButton(0))
            ball.GetComponent<Rigidbody>().AddForce(Camera.main.transform.forward * thrust);        
          
    }
}

But this script does nothing. Can you tell me what is wrong? Am I on right track at least?
thank you in advance.
