title: How to develop a scrollview with inertia in Unity?
body: <p>I want to develop a "scrollview" in Unity.</p>
  
  <p>Basically I have a Parent Game Object on the screen with many items inside it.
  The Parent Game Object is big enough so it goes outside the screen.</p>
  
  <p>I developed a scrolling script so when the user drags the parent object, I move it and it looks like scrolling.</p>
  
  <p>I did this by implementing the OnMouseDrag event.</p>
  
  <p>How can I calculate the inertia and apply it so when the user drags it fast, it continues to move?</p>
