transform.forward not working correctly?

I am a beginner to using unity, so this is probably a simple mistake. I want to move my player forward in my game, but transform.forward doesn't point forward when the object I put the script on is rotated?

 inputY = Input.GetAxisRaw("Vertical") * Time.deltaTime;

             if (inputY > 0){
                 
                 rb.velocity = transform.forward * speed;
                 
             }
