Help with fire script

When I shoot the gun it only shoots one way no matter what direction I'm facing

My script on the gun

 public GameObject bullet;
 public float fireRate = 10f;
 private float nextFire = 0.0f;
 public float bulletSpeed = 100f;
 
 void Update()
 {
          if (Input.GetButton("Fire1") && Time.time > nextFire)
 {
 nextFire = Time.time +firerate;
 GameObject Bullet = Instantiate(bullet, transform.position, transform.rotation) as GameObject;
 Bullet.rigidbody.AddForce(Vector3.forward * bulletSpeed);
 }
 }
 }

My script on the bullet

 Public GameObject spawnPoint;
 
 void  Update ()
 {
 Destroy (gameObject, 5);
 }
 Void FixedUpdate()
 {
 rigidbody..AddForce(Vector3.forward * 100);
 }
 }
