title: AS3 rotate start speed then slow down over time
body: <p>I got this code that makes my object rotate continuously</p>
  
  <pre><code>movieClip_2.addEventListener(Event.ENTER_FRAME, fl_RotateContinuously_2);
  
  function fl_RotateContinuously_2(event:Event)
  {
      movieClip_2.rotation += 100;
  
  }
  </code></pre>
  
  <p>How can i get this object to slow down over say 5 sec from 100 to 10?</p>
