Yes, if you think you have hit your ball in play out of bounds you must play a provisional ball from the exact same spot as where you played the previous shot from. However, if you know the ball is out of bounds the next ball you play becomes the ball in play.

There are many sports that use a ball, believe it or not but balls have a long history and can be used in various ways. Bouncing is basically the main source to a ball. The question is "what makes a ball bounce". Let's say you were to drop a ball in slow motion, video tape it, or watch the ball closely, you would actually see the ball change its shape. When the ball hits the ground it flattens. Then when the ball comes up it returns to its original shape, this is because of forces and energy. When you drop a ball gravity pulls it toward the floor, the ball gains energy of motion, acknowledged as kinetic energy. When the ball hits the floor and stops that energy has to go "somewhere." The energy goes into deforming the ball-from its original round shape to a squashed shape. When the ball deforms its molecules are stretched apart in certain places, but in other places the molecules are squeezed together. I believe that other than gravity the ball bouncing flat is what helps the ball bounce back up. Does how much air that is in a ball change how high, low, fast, or slow the ball bounces? How much air in a ball does have a great affect on the ball. If you have no air in your ball, how will it bounce back up? When you let the ball go to hit the ground the ball is suppose to bounce back up, but if you have "no'' air in your ball and you let it go the ball might change the shape but it wouldn't bounce back up to you. If you were to have a lot of air in your ball then when you are letting the ball go, the ball will bounce back up and down, a lot of the times a human only has to bounce a ball once for it to bounce at least 3-6 times on its own.

Nine ball (pool)

you don't do anything. you can't control the ball and ball sack size.

if a batted ball bounces in the infield and crosses over any part of 1st or 3rd base it is to be ruled a fair ball. If the ball has not bounced on the infield, the call is made depending on where it first touches the ground. if in fair territory or on the line it is a fair ball, outside the line is a foul ball. Any ball that physically hits 1st or 3rd base is a fair ball
