Hi good and wise people. Please, help the beginer. I can't figure out how to stop object after AddForce. My script is

var Cube : GameObject;
var Sphere : GameObject;

function Start(){
    Cube = GameObject.Find("Cube");
    Sphere = GameObject.Find("Sphere");
}

function OnTriggerStay (other : Collider) {
    if(other.transform.name == "Sphere"){
        Sphere.rigidbody.AddForce (1, 0, 0);
    }
}
function OnTriggerExit (other : Collider) {
    if(other.transform.name == "Sphere"){
    Sphere.rigidbody.AddForce (0, 0, 0);
    }
}

where Cube is a trigger. Sphere exits the Cube and still moves. I there any way to remove the AddForce? Thanks :)

What if you AddForce in the opposite direction?
