No. In addition to slight difference between models and /manufacturers, there are generally 3 type of cue balls. The normal regulation play ball that is not intended for use on a coin operated table is most common and is what should be used to learn and practice cue ball control. Cue balls made for use in coin operated machines need a way to be released so they are not captured like the numbered balls - so, these cue balls are either larger (no longer common) or have a metallic center (slightly heavier than a standard cue ball).
If you take 4 balls and there are only 3 colors, there is no way you cannot get 2 of the same color. So 100%
American footballs and Rugby balls are both considered 'balls' but neither are spheres.
Basketballs, Baseballs, Golf balls, some bouncy balls, a Globe, and things that carry that same shape. :)
Depending on the sport, balls could be made of : Plastic, rubber, composite or all natural materials.
They equal the same
The cue stick is used to strike the balls. The cue ball used by the players to hit the other balls is the white ball. It is the one they hit with the cue stick.
There are two types of cue balls - those made for regular play on a conventional pool or billiards table and those made for use on a coin operated table. The center of the cue ball is of the same material as the surface unless it is a cue ball specifically intended for use on coin operated tables. The coin table cue balls today are either larger but of the same materials, or are magnetic. The majority of coin table cue balls today have a magnet inside that prevents it from being "trapped" the way the numbered balls are when they are pocketed, so that it returns to the player.
There is no difference between the cue ball and billiard ball except that the cue ball is white and without significant markings.
The Cue Ball is less weight than the Colored Balls.
Both are the same weight in most cases. For coin operated tables, most tables today use a magnetic cue ball which is slightly heavier than the numbered balls. It also can mean the it is a bit harder to control the cue ball. Older coin operated tables used a larger cue ball, not magnetic, which in addition to weighing more than the numbered balls, creates other cue ball control problems.
No, in 8 ball and straight pool there are fifteen numbered balls plus the cue ball.
The number of balls depends upon the game. All balls use a cue ball plus 7, 9, 15, or 21 numbered balls.
The pool STICK,billiard pool stick or pool cue stick all refer to the stick that is used to play pool with
The lights are there for the same reasons all lights are used; to light the table evenly so there is no shadows from the balls, cue, or player (if lighted properly).
Different numbers for different games. 8-Ball has 15 numbered balls and one cue ball. 9-Ball has 9 balls and one cue ball.
Baseball, a pocket billiards game, uses 21 numbered balls following the same color scheme as the first 15, and a cue ball.
Since you haven't given us any options - the one relating to friction is the correct answer !
