how can i make drag and release (like billiard games) ball control

There's a couple ways of doing this. Here's one.

• Make sure your ball has a rigidbody component, you'll need to apply forces to it.

• Be ready for a lot of troubleshooting when multiplying the force times the delta.magnitude of mouse distance from original position.

Here's some code in C# to get you started:

 Vector3 delta = Vector3.zero;
 Vector3 lastPos  = Vector3.zero;
     
     void Update()
     {
         if ( Input.GetMouseButtonDown(0) )
         {
             lastPos = Input.mousePosition;
         }
         else if ( Input.GetMouseButton(0) )
         {
             delta = Input.mousePosition - lastPos;
             
             Debug.Log( "Delta Distance From Starting Position : " + delta.magnitude );
 
             //multiply delta.magnitude times the force you want to apply to the ball and bam! magic!
 
         }
     }
