I have no idea why it isnt moving. I dont even get any errors.

using UnityEngine;
using System.Collections;

public class RocketPropulsion : MonoBehaviour {
	public float speed; //meterspersecond
	public float burnTime;//How long is the rocket have thrust for?
	public float spinRate;//How many rotations per second
	public float velocityAtLauncherExit;//how fast does it exit the launcher
	public float accelerationInitial;
	public float accelerationFinal;
	public Rigidbody rocket;

	//Technical data for the rocketMotor
	void Fixedupdate(){
		Rocket ();
	}

	// Use this for initialization
	void Start () 
	{
		GetComponent<Rigidbody> ();
	
	}

	// Update is called once per frame

	void Rocket () 
	{

		rigidbody.AddForce(rocket.transform.up * speed * Time.deltaTime);//fires the rocket at the defined speed going in meters per second.
	
	}
}

I found the problem. I forgot to capitalize the u in fixed update I wrote it like Fixedupdate should have been FixedUpdate. XD
