Why when spinning object I need to set the speed value to 2000 to make it spin fast? : I want it to spin at speed from 0 to very fast. 
But if I'm changing the value of the spin to 10 it's almost not moving and 200 make it move slowly. 2000 make it move fast. But why only when changing to 2000 it's spinning fast ? 

    public float rotationSpeed;
    
    private void Update()
        {
          scaling.objectToScale.transform.Rotate(Vector3.up, rotationSpeed * Time.deltaTime);
        }
