Why does some accelerating body stop when an opposite force is equal to it and some others will continue at constant velocity?. For example, say a book at some height above the ground is against a wall is released from rest. The book will always slide down even if the friction between the wall and the book is equal to the weight, right? But let's now say we rub glue on the wall between the book and ground. This time if the glue is strong enough, it brings the book to a stop, making it hang on the wall.
Another example could also be a falling inflated balloon in air. The balloon keeps falling even when drag force equal gravity. While say the balloon were charged(rubbed with fur), and an electric field equal equal to gravity is introduced it hangs on the air.
Why is this happening? Is there something else that determines this outcomes?
