A tennis ball, when impacted, dissipates about 45% of the energy applied to it. This means that it only absorbs and returns 55% of that energy. That is why in the test standard for tennis balls, dropping it from 100 inches, it only rebounds 53 to 58 inches. It is returning that much energy. The strings of the racket, however, return 90% of the energy they are impacted with. So, when the tennis ball hits the strings and they stretch (absorb the energy), they will return 90% of that force in the return of the ball. When a ball hits strings with a higher tension, the force is exerted on the ball, instead of the strings, and the energy return is closer to the 55% range.
yes it does it has been proven also DERP that was random but yes a tennis ball bounces best on concrete
To hit a tennis ball with topspin, at the point of contact with the racquet being perpendicular to the ground, twist your wrist so the face of the racquet with the point of contact with the ball turns towards the ground. You must do this while you are swinging at the ball. Follow through with the ball, which means do not stop as soon as you hit the tennis ball and twist your wrist, but rather let the momentum let you take the racquet more forward after contact with the tennis ball has ceased. The best way to generate topspin is the "high-to-low" concept, by starting with your racquet low and ending up higher. View the Related Link to see a YouTube video of topspin demonstration.

The one(S) in your racquet...nut bar
The size of tennis racquet you choose is really a personal preference. Basically, tennis racquets come in a mid-size and oversize. The mid-size racquet has a smaller tennis face and less surface area of tennis strings. Mid-size racquets are more compact and usually lighter. They are easier to swing and move around quickly. Serve and volley type players often prefer the smaller mid-size racquet. An oversize racquet has a large surface area of tennis strings. This can make the racquet feel heavier and it is more difficult to swing the racquet around quickly. However, the "sweet" spot on the racquet is larger. The sweet spot is where you want the ball to hit your strings more maximum effectiveness. Players that hug the baseline tend to enjoy using an oversize racquet. You can always "demo" different racquets at your tennis club to see which size is best for you. Your tennis pro can also give you great reccomendations.
A local racquet club is a great place for tennis lessons. You can learn all the rules of the game and the scoring system. Also, you will learn the proper stances for hitting the ball.
For most of the best racquets used by professionals preferred material is graphite.
If you drop it from a certain height the first bounce will be ideally about 90% of height, at best, on a smooth hard surface, or 0.9 h. On the tenth bounce it is 0.9 to the 10th power or about 35%,or 0.35 h.
it depends on what works for you, but the number one tennis player, Novak Djokovic uses the head tennis racket, and it works really good for him.
