Answer 1

my question is called overscrolling,using this config:

scrollable : {
      momentumEasing:  {
         momentum: {
           acceleration: 30,
           friction: 0.5
         },
         bounce: {
            acceleration: 0.0001,
            springTension: 0.9999,
         },
         minVelocity: 5
      },
      outOfBoundRestrictFactor: 0   
      }
