Projectile clones not moving forward

Hello everybody, okay so I was following this tutorial to set up Instantiate in my 2d side scroller game that I am making…http://unity3d.com/learn/tutorials/modules/beginner/scripting/instantiate
I feel like I must be making some stupid mistake. The clones of the projectile just stay in place where my character is at any given time… I have kinematic set to off and I tried changing the RocketPlace transform position to see if it was facing the wrong direction… totally stumped on this and not sure what to do… any insight? Thank you -Gene

using UnityEngine;
using System.Collections;

public class UsingInstantiate : MonoBehaviour
{
    public Rigidbody rocketPrefab;
    public Transform barrelEnd;


    void Update ()
    {
    if(Input.GetButtonDown("Fire1"))
        {
            Rigidbody rocketInstance;
                rocketInstance = Instantiate(rocketPrefab, barrelEnd.position, barrelEnd.rotation) as Rigidbody;
            rocketInstance.AddForce(barrelEnd.forward * 5000);


    }
}
}

Okay I figured out my mistake for anybody who might have the same issue… I had a rigid body on my rocket prefab and had kinematic checked… DOH!
