In tennis, the average speed of a serve for a man can range from from 70mph up to the world record of 163.7 mph. A pro would average in the high end, 120-130mph.
As of March 2014, the fastest professional serve speed for a man is held by Samuel Groth at 163.7mph (263.4 km/h). This was set at the 2012 Busan Open Challenger Tennis.
Additionally, other top speed servers include:
Height does seem to play a factor in how fast a player can serve the ball.
The fastest volleyball serve ever recorded was made by GyΓΆrgy Grozer, a Hungarian volleyball player, with a speed of 134 km/h (83.5 mph) during a match.
Could be referring to the time limit (ten seconds) the server has to serve the ball once the whistle has blown. Could also refer to the rule changes that have been implemented to speed up the game, such as scoring on every serve regardless of which team serves.
A volleyball serve typically involves a third-class lever, where the effort is applied between the load (the ball) and the fulcrum (the server's arm joint). This lever allows the server to generate speed and power for the serve.

It is hard to determine what the average speed of a tennis serve is from various players, but Sam Qurrey is among the fastest serves of all time. He has recorded a serve of 141 miles per hour at multiple events.
speed helps alot in volleyball because you have to have speed to get to the ball, and you have to be able to give the ball speed while spiking, pushing, and serving. ****
It's measured because the first serve speed is a very important statistic. The faster a serve is, the harder it is for the opposing player to return. By knowing a person average first serve speed, you can then decide on what kind of strategy you can use to return the serve and win the point
Betweeb 200Km/h to 210Km/h but fastest Andy Roddick's serve is 249Km/h !
its more difficult than an underhand serve because you throw it in the air and try to hit it. its more easier to do an underhand serve because you hold it your hand rather than throwing it in the air. its more dangerous because it goes in a faster speed than an underhand serve.
Velocity is the speed of something in a given directionin volleyball there is a club called velocity
I don't recall who but in the 08 Olympics Men's Volleyball, Bulgaria vs Russia, the fastest serve I saw was a Matei Kaziiski serves it was 137 kph, which is 85 mph. Retired beach volleyball player Louis O'Rear of Cantonment, Florida was clocked at 88 mph on Pensacola Beach. He now teaches science at Ransom Middle School.
It depends on how hard the spiker hits it.
