because humans have arms and legs, and tennis is a SPORT where you have to run (legs) and hit the ball HOLDING a raquet (arms!)
haha
When playing tennis, the arm is used as a 3rd class lever. Also, you can research how the human body reacts to such strenuous sporting activity.
None. Neither a tennis ball, nor tennis, are essential to human survival. There is no "use".
I think my A-level biology teacher said "About 2 Tennis Courts" but that was a few years ago
The human lungs have roughly the same surface area as a tennis court if they were to be laid out. This is 2,808 square feet, or 260.87 square meters.
Yes, SPIN. With spin you can do spin. With bat. And the in another side human will not hit the ball.

Aerobic endurance or aerobic capacity is important to a tennis player. Tennis is a sport which requires both mental and physical fitness. The mental and physical abilities of a player complement each other whether for the better or for the worse. The brain and all parts of the human body require adequate amounts of oxygen for proper functioning. Tennis is played at higher levels when the player is working with a well oxygenated brain and body. If the human body is oxygen deprived, or goes into a state of oxygen-debt, the tennis player loses the ability to focus the mind properly, or to pay good attention. Aerobic endurance, as it applies to tennis, means that a tennis player has well developed lungs with the output capacity to supply the oxygen needs to the entire body, without interruption, during even the most demanding of points of any game.
