Code:

       second = 0;

       float objMass = llGetMass();
       float Z_force = 10.2 * objMass;
        
       llSetForce( < 0.0, 0.0, Z_force >, FALSE );

       {   // then let gravity take over, and change color to green.
           llSetForce( < 0.0, 0.0, 0.0 >, FALSE ); 
           llSetColor( < 0, 1.0, 0 >, ALL_SIDES );

       }

       {

           llSetColor( < 0, 0, 1.0 >, ALL_SIDES ); // change color to blue.
           llSetForce( < 0, 0, 0 >, FALSE );

           // ...move object back to starting position...
           // ...after saving current status of Physics attribute.
           integer savedStatus = llGetStatus( 1 );
           llSetStatus( 1, FALSE );  // turn physics off.
           while ( llVecDist( llGetPos(), startPos ) > 0.001) 
           {
               llSetPos( startPos );
           }
           llSetStatus( 1, savedStatus );  // restore Physics status.
           
           //...and then turn color to black and Reset the script.          
           llSetColor( < 1, 1, 1 >, ALL_SIDES );
           llSetTimerEvent( 0 );  // turn off timer events.
           llSay( 0, "Done and resetting script." );
           llResetScript();  // return object to ready state.
       }
   }
}

Status: Not working. Missing llSetStatus(), llSetForce(), and llGetMass(). Physics engine is not currently fully implemented.
