title: Objects that defy gravity but collide with others in Box2D. How?
body: <p>newbie to iPhone game development and Box2D here.</p>
  
  <p>I'm developing a game in which I can move (drag) otherwise stationary objects that can collide with other objects.</p>
  
  <p>How do I make these objects stationary in a Box2D world with gravity while maintaining their ability to collide with dynamic bodies?</p>
  
  <p>One random thought is to exert a force equal to gravity on these objects all the time. Any better or simpler approaches? Will static bodies help?</p>
