body: <p>What does the term "STEP" means in bullet physics?</p>
  
  <p>What does the function <code>stepSimulation()</code> and its parameters mean?</p>
  
  <p>I have read the <a href="http://bulletphysics.org/mediawiki-1.5.8/index.php/Stepping_The_World" rel="nofollow">documentation</a> but i could not get hold of anything.</p>
  
  <p>Any valid explanation would be of great help.</p>
