Learn the basics of tennis scoring. One player serves the ball per game. From the time the ball is served, one point is available to either player. The point is awarded when the ball goes out of bounds, hits the net, or is missed by a player. The game ends after one player has scored four points with a margin of at least two points over the loser. For example, a score of 4 - 2 means that the game is over, but a score of 4 - 3 means that the game must continue.[5]

So to answer the question – there are many balls because motor learning (learning how to hit and move) takes many repetitions and the coach is ready for that. He also knows that you will probably miss many times before you get the right feel. It's not a life or death question, it's just learning to move in a new way. Are you ready to start with tennis for beginners and do you have realistic expectations?

Balls wear out quickly in serious play and, therefore, in ATP and WTA tournaments, they are changed after every nine games with the first change occurring after only seven games, because the first set of balls is also used for the pre-match warm-up.[45] As a courtesy to the receiver, the server will often signal to the receiver before the first serve of the game in which new balls are used as a reminder that they are using new balls. However, in ITF tournaments like Fed Cup, the balls are changed in a 9–11 style. Continuity of the balls' condition is considered part of the game, so if a re-warm-up is required after an extended break in play (usually due to rain), then the re-warm-up is done using a separate set of balls, and use of the match balls is resumed only when play resumes.

Ego/fear=childISH and constrictive. Playful is ChildLIKE allows freedom from ego which results in ease and natural power. The adult self can choose when to let go. When and where it is safe. A tennis court is a safe universe with lines and rules. Those rules allow play without anxiety. Embrace the parameters and have fun. You’ve already won the hardest part and it works! (OK..I still swear my arse off, in a garbled language somewhere between a Glasgow dockyard and Babylon when I miss, but that’s fun too).
If you find reading boring then you can try watching free instructional videos on the internet. The best part about these videos is that it is made by tennis pros who are passionate about teaching tennis, so you won’t find the videos hard to understand. Between reading and watching the instructional videos, you will pick up important details about tennis on your own.
The score of a complete match may be given simply by sets won, or with the scores in each set given separately. In either case, the match winner's score is stated first. In the former, shorter form, a match might be listed as 3–1 (i.e. three sets to one). In the latter form, this same match might be further described as "7–5, 6–7(4–7), 6–4, 7–6(8–6)". (As noted above, an alternate form of writing the tiebreak score lists only the loser's score—e.g., "7–6(6)" for the fourth set in the example.) This match was won three sets to one, with the match loser winning the second set on a tiebreaker. The numbers in parentheses, normally included in printed scorelines but omitted when spoken, indicate the duration of the tiebreaker following a given set. Here, the match winner lost the second-set tiebreaker 7–4 and won the fourth-set tiebreaker 8–6.

The concrete slab should be placed at a thickness of at least 4 inches, or 5 inches if subject to repeated freeze/thaw cycles. Munson's post-tensioned slabs are a minimum of 5 inches thick, with the post-tensioning cables spaced 3 feet apart. Before installing the slab, Munson lays down two layers of 10-mil polyethylene sheeting to reduce drag as the slab shrinks upon curing and to serve as a moisture-vapor barrier.
Another theory is that the scoring nomenclature came from the French game jeu de paume (a precursor to tennis which initially used the hand instead of a racket). Jeu de paume was very popular before the French Revolution, with more than 1,000 courts in Paris alone. The traditional court was 90 ft (pieds du roi) in total with 45 ft on each side. When the server scored, he or she moved forward 15 ft. If the server scored again, he or she would move another 15 ft. If the server scored a third time, he or she could only move 10 ft closer.[7]
It is all based on how comfortable you are with the racket. If the racket works well with you, it is a good one. Are you hitting too many frames? Too many nets? Too many outs? Too many faults? No? then your racket is fine. Can you hit a good strong shot without the need for any strenuous effort on your part? Can you smash with the racket without your arm getting sore? Can you hit a nice serve with the right spin? If yes, you have a good racket.
In the U.S. in 1874 Mary Ewing Outerbridge, a young socialite, returned from Bermuda with a sphairistikè set. She became fascinated by the game of tennis after watching British army officers play.[18] She laid out a tennis court at the Staten Island Cricket Club at Camp Washington, Tompkinsville, Staten Island, New York. The first American National championship was played there in September 1880. An Englishman named O.E. Woodhouse won the singles title, and a silver cup worth $100, by defeating Canadian I. F. Hellmuth.[19] There was also a doubles match which was won by a local pair. There were different rules at each club. The ball in Boston was larger than the one normally used in New York.
