My Character not coming to ground after Jump

Dear Friends,

I am Sorry for the simple question, I have prepared one model in blender and imported it in unity and wants to make ThirdPersonController.

  1. I have added the model in the scene and added component → Rigidbody, Capsule Collider, ThirdPersonCharacter(Script), ThirdPersonUserControl(Script), , which is all by default.

  2. I have uploaded the video on this url also - http://tinypic.com/r/34hw8jo/9 for better understanding, here in the last, you see , when i click on space, it jumps but does not come back to ground.

  3. I dont know what i am missing ?? , Please help me in this regard

Thankyou

From what I can tell, you have forgotten to enable useGravity on the rigidbody component. Gravity will move your character down at the rate-per-sec specified in the menu found in Edit → Project Settings → Physics until the collider hits something.
