Tennis racquets with old type of strings did not allow power and control over the racquet at the same time. To get a powerful stroke player had to hit the ball with the area of racquet closer to the tip of the racquet (toe). To obtain control and to reduce vibration of the racquet, player had to hit the ball with the area of racquet called “sweet spot”, located around the geometric center of the head. NASA’s 1973 Skylab 3 mission showed that tapered strings can move the “sweet spot” from the center of the racquet toward the position of greater power.
The NASA research on spider webs, which was meant to find the solution to reduce the vibration on space stations, unexpectedly benefited tennis. NASA’s Skylab, the first U.S. space station, in 1973 carried out the experiment with the space born spiders Anita and Arabella, to learn from spiders how to construct low vibration space stations.
Soviet space station Mir had serious problems with vibration. Every use of exercise equipment caused the entire station to shake. Spiders are well known for making their nets capable to absorb the impact of their pray. According to the book “The Web of the Spider” by Laura Barr Lougee , spider webs are made in such a way to keep all tensions in balance. The NASA research showed that the change in diameter of strings changes the stability of a network. This property of strings was used to improve the performances of tennis racquets.
It is hard to define “power” of racquet. According to  power could be defined as
1. racquet bounce (high coefficient of restitution)
2. high swing weight (high angular momentum)
3. low work (racquet which gives the greatest ball speed with a given player effort)
The easiest way to understand power is the coefficient of restitution (COR). The maximum power occurs when the COR is the greatest.
The coefficient of restitution is the ratio of the differences in velocities before and after the collision. COR is defined as difference in the velocities of the two colliding objects after the collision, divided by the difference in their velocities before the collision.
COR = coefficient of restitution
= linear velocity of the racquet mass center before impact
= linear velocity of the ball before impact (will be negative according to our convention that away from the player is positive)

- Physics of Tennis The most principal piece of the sport of tennis is the rally, where adversaries progressively hit the ball forward and backward over the net, utilizing their tennis racquets, until one player makes a slip. Amid a rally, there is an astounding cluster of essential mechanical standards in progress that represent the direction or the ball. The motion of movement of a tennis ball are represented by the same fundamental mechanical rule. In any case, the sheer number of power communications that happen on a tennis ball make it difficult to effectively determine a basic scientific comparison for the flight way of a tennis ball once it has been hit by a racquet....

- Tennis vs. Golf I 'm going to compare tennis to golf to reveal the similarities and differences between the two sports. I think you will be surprised how similar they are. They both depend on the swing of your body; grips of your hands, the strike zone of the ball and both are a mental game. Tennis and golf are also very different in many ways. The types of balls used to play the game, materials used to make the balls and equipment used to hit the balls. Tennis is a team sport and an individual sport....

- Tennis is one of the most popular sports in the world, mainly due to its ease of play and universal appeal. It is also an Olympic sport which is played at all levels of society and at all ages. Aside to that, tennis is the most major spectator sport because of the four Grand Slam tournaments: the Australian Open, the French Open, Wimbledon and the US Open. Going back in history, the earliest form of tennis was seen in a game created by the 12th century French monks, who were looking for entertainment inside the monastery....

= linear velocity of the racquet mass center after impact
= linear velocity of the ball after impact
From the coefficient of restitution formula, it follows that
To find the coefficient of restitution in the case of a falling object bouncing off the floor, or off a racquet on the floor, we can use the following formula:
where: is rebound height
is initial height
According to , the highest coefficient of restitution (power) is near the tip of the head.
COR (center of mass): .74162
COR (near the throat): .63246
COR (tip of the head): .7746
Sweet spot is the position of optimum vibration. When the ball hits the sweet spot player does not feel the impact of the ball, because a minimal kick or jar is transmitted to the player's hand. The strings absorb the vibration that increases stability of the racquet in the player's hand and player has more control over the racquet.
“The sweet spot is determinative of the force from impact: the higher the sweet spot, the lower the Impact Force acting at the racquet's mass center, and the more positive the Impulse Reaction” 
Dr. David Noever a research scientist at the NASA Marshall Space Flight Center in Huntsville, Alabama, used two space born spiders, Anita and Arabella in Skylab 3 mission to study the way in which spiders span their webs in space. The objective of that experiment was to learn how to make a low vibration network of strings in outer space. The resulting network would be used in the construction of future space stations. The outcomes of the research showed that spiders born in space, in microgravity conditions made their webs with treads of different diameters. In contrast, spiders on the Earth make trends of the constant diameters.
The March 1995 issue of NASA Tech Briefs in the article “Improved Tennis Racquets Have Tapered Strings” explains some results of the Skylab 3 mission experiment
“Research found that changing the diameters of strings could radically change the stability of a network against vibration” 
Strings of different diameter have different properties. Thicker strings are stronger than but not as elastic as thinner stings.
In old wooden frame racquets the sweet spot was at the geometric center of the racquet. But new method of tapered string made it possible to move the sweet spot toward the toe of the racquet.
According to Racquet Research web site , longer distance from the hand to the sweet spot is better. This improves the performance of the racquet by combining the stability and controllability of the racquet and power.
