title: What effect does "wake" have in b2Body::ApplyLinearImpulse?
body: <p>I am using Box2d v2.3
  The following box2d method takes a bool "wake" :</p>
  
  <pre><code>inline void b2Body::ApplyLinearImpulse(const b2Vec2&amp; impulse, const b2Vec2&amp; point, bool wake)
  </code></pre>
  
  <p>What does it do? Regardless of whether I set it to YES or NO, it doesn't seem to noticeable 
  impact my physics.</p>
  
  <p>Earlier versions of Box2d did not accept the bool - they only took impulse and point.</p>
  
  <p>EDIT: Likewise so does the following method:</p>
  
  <pre><code>inline void b2Body::ApplyForce(const b2Vec2&amp; force, const b2Vec2&amp; point, bool wake)
  </code></pre>
