Better way to script AddForces in 2 axis

How is the better way to write this script to apply 2 forces on Axis. As I'm not a programmer I wrote 1 line for each force. Tks

Code (csharp):

1. function Update () {
2.  
3.  if (Input.GetKeyDown ("space")) {
4.  
5.         var tempBullet1 : Rigidbody;
6.  
7.         tempBullet1 = Instantiate(bullet1, transform.position, transform.rotation);
8.         tempBullet1.rigidbody.AddForce (Vector3.forward * 2000);
9.         tempBullet1.rigidbody.AddForce (Vector3.up * 500);
10.  
11.     }
12.  
13. }
