To Hit An Ace
At the 2010 Wimbledon match between John Isner and Nicolas Mahut, Isner set the record for the greatest number of aces in a match at 113. An ace is considered a legal serve that is not touched by the receiver, resulting in a point for the server.
Amazing But True
- A legal serve in tennis is one where the server hits the ball across the net into the service court on the opposite side of the center service line. The ball has to enter within the legal dimensions of
6.4 m×4.11 m.
- The speed at which the tennis ball is hit greatly determines the angle necessary for the ball to pass the top of the net. This delicate balance between variables is what separates great tennis players from the best. Use the diagram below to answer the following questions about this relationship.
Can You Apply It?
