title: Unity - Object spins after collision
body: <p>When my sphere collides with a tree of the terrain, the sphere spins around. I tried to freeze Z position und rotation, but it still spins after collision. Here is the move script:</p>
  
  <pre><code>player.transform.Translate(Vector3.forward * speed * Time.deltaTime);
  </code></pre>
  
  <p>Speed is 10f. Thanks forwards.</p>
