title: Unity physics about collision and energy
body: <p>I have been working on a Unity ping pong game using the Leap Motion. I use <code>rigidbody.MovePosition()</code> to move the paddle. However, when I hit the ball (which uses gravity), the paddle launches it too far. Even when I change the masses of both, it doesn't do anything. </p>
  
  <p>What variable should I change to reduce this energy going into the ball?</p>
