Accelerate ball over time

I have a ball which need to accelerate during time, but give a very little force. I tried to accelerate with Time.deltatime divided with specific values but it doesn't work.

This is my sample of code (to start game, you need a one tap and ball is moving with constant speed) and my question is how can automatically accelerating a ball during time.

void Start () 
{   
    Application.targetFrameRate = 60;
    gameStart = false;

}

void Update ()
{
    if (!gameStart) 
    {
        if (Input.touchCount >= 1) 
        {
            gameStart = true;
            GetComponent<Rigidbody2D> ().AddForce (new Vector2 (1f, 0.5f) * force);


        }
    }
}

You can try this, I have not changed any variable names to maintain familiarity with your original code 

Rigidbody2D myRigidbody
void Awake(){ myRigidbody = GetComponent<Rigidbody2D>(); }

void Start () 
{   
    Application.targetFrameRate = 60;
    gameStart = false;

    // Invokes the method setGameStartToFalse in 2 seconds, then repeatedly every 1 seconds.
    InvokeRepeating("setGameStartToFalse", 2f, 1.0F);
}

void FixedUpdate ()
{
    if (!gameStart) 
    {
        if (Input.touchCount >= 1) 
        {
            gameStart = true;
            myRigidbody.AddForce(new Vector2 (1f, 0.5f) * force);
        }
    }
}

void setGameStartToFalse()
{
    gameStart = false;
}

In Update() method you set gamestart to true so the application will not execute the code inside the first if until you will set again gamestart to false. You also must check that MonoBehaviour is enabled or Update will not execute
