Answer»

I didn't understand what you are SAYING?

literally the speed of ball will continuously decrease due to gravitational force which is continuously acting on the object. At a POINT of time the speed of ball BECOMES zero due to the gravitational force but later it falls back because now the gravitational force is SUPPORTING the motion of the ball & the speed of the continuously increase until it hit the ground
