Unity2d android. Box keeps moving after taking away accelerometer controls

My Rigidbody2d continues to move whichever direction my accelerometer was moving even after i destroy the script for the controls. How can i make it so the accelerometer stops adding force after i destroy it?

Here's my current code

 #pragma strict
 
 function Start () {
 
 }
 
 function OnCollisionEnter2D(coll: Collision2D) {
         //Destroy the script for the controller after he hits the ground
         Destroy (this);
         
         
         
      
     }
 
 var forceVec: Vector2;
 function FixedUpdate () {
 //Moving players x by the rotation of the phone
 rigidbody2D.AddForce(Input.acceleration.x * forceVec);
 
 
 }

I just began unity like a week ago so it might be a very novice mistake.
