The white ball is slightly smaller than the rest of the balls so when it goes down a pocket it falls into a hole that the other balls roll over. This brings the white ball to the top of the table and the other balls into the dispenser. You'll see it if you lifted the slate off the table.

The potential energy of the book decreases as it falls off the table and its height decreases.
If you're referring to a foul, it's ball in hand for the incoming player, provided it is a cue ball foul (i.e. scratch, ball off table, hitting opponents ball before your own, etc.). I believe some fouls result in loss of turn, but not ball in hand (i.e. - an object ball leaves the table).
The potential energy of the ball (due to its position on the table) transforms into kinetic energy as it rolls off the table and falls. When the ball hits the floor, some of the kinetic energy transforms into elastic potential energy as the ball compresses and then rebounds. Finally, friction and air resistance gradually dissipate the ball's kinetic energy into thermal energy, causing it to stop.
Yes, the time it takes for the ball to hit the ground will depend on the initial speed at which it rolls off the table. A ball rolling off the table with a higher initial speed will hit the ground sooner than a ball rolling off with a slower initial speed, assuming all other factors remain constant.
The horizontal velocity of a ball remains constant after it rolls off a table if we assume no horizontal forces act on the ball. This is due to the principle of inertia: an object in motion will remain in motion at a constant velocity unless acted upon by an external force.

Not exactly. In 8-ball, anyone can hit the 8-ball into a pocket AFTER all of their balls are off of the table. For example, if you are stripes you cannot hit the 8-ball into a pocket while there are striped balls on the table. If you do, you lose. Some people play the game of 8-ball with the 8-ball being neutral, meaning you can hit the 8-ball first when making combination shots.
When a book falls off the table, it changes from a state of rest to a state of motion. Gravity is the force acting on the book that causes it to fall.
When a ball bounces off a table, the initial potential energy is converted to kinetic energy as the ball falls towards the table. Upon impact, some of this kinetic energy is converted back into potential energy as the ball compresses slightly, before being translated back into kinetic energy as the ball bounces back up. Some energy is also lost to sound and heat during the bouncing process.
