The Difference Between: Hard, Clay and Grass Tennis Courts

🔔TURN ON NOTIFICATIONS TO NEVER MISS AN UPLOAD!🔔 - This is the difference between Hard, Clay and Grass courts, you can see why Djokovic is soo good on Hard, Nadal on Clay and Federer on Grass. Strange that Hard courts are faster these days than grass courts. My question is: it is the speed of the court that is slowed down or the technology of the racquets has become much better and the players are able to hit the ball much harder more easly? - Hard Courts Hard Courts are courts generally made from asphalt or concrete and are the most commonly available courts as they are easy to maintain. The Hard Court provides a surface where: 1. the ball travels at a speed slower than on Grass Courts but faster than Clay Courts; 2. the bounce of the ball is high due to the hard surface; and 3. the bounce of the ball is very predictable as the surface is very flat and easy to maintain. The Hard Court is generally considered by the International Tennis Federation (ITF) as a good surface for all types of players as it provides a good compromise between the Grass Courts and Clay Courts and is thus termed as a “Democratic Court”, which provides players favouring various styles of play, from the Serve and Volley player to a Baseliner, thus providing an even playing field. Despite the proclamation by the ITF, experts have express opinions that the Hard Courts favour players with a good serve as the surface is still considered generally fast and base line players (players who enjoy long rallies) as the bounce of the ball is high and predictable. - Grass Courts The Grass Court is normally associated with the prestigious Wimbledon Championships, which take place every July, a tournament which has been graced by the greatest names in tennis such as Roger Federer, Pete Sampras and John McEnroe. This surface is the fastest of all the tennis court surfaces due to its slippery surface. The ball has a lower bounce as the soil is softer than the materials used on the other types of tennis courts. The Grass Courts may also produce an unpredictable bounce to the ball due to the softer and slightly uneven surface of grass. Due to the characteristics of the Grass Courts, the ball moves at a faster pace with a lower bounce thus favouring players with a good serve and net players. -Clay Courts The deep red coloured Clay Courts are synonymous with the French Open Championships. These courts are considered the slowest surface in tennis as the Clay surface: 1. slows down the speed of the ball; 2. reduces the skid of the ball on the surface of the court; and 3. causes a high bounce of the ball. Due to the these characteristics, the Clay Courts reduces the speed of a ball which is hit by hard hitters as it slows down the speed of the ball, making it easier for an opponent to return the shot. This may explain why players such as Pete Sampras, who favours the serve and volley game, has never won the French Open Championship (the only Grand Slam played on a Clay Court) despite his dominance of the Grass and Hard Courts in the 1990s. Clay Courts are favoured by baseline players and players who generate heavy spins on their shots, example of such players are Michael Chang and Rafael Nadal who is often dubbed the King of Clay. ◆◇◈ SUPPORT THE FAM! ▶ Subscribe: https://goo.gl/DKfo4v 💬 Telegram: https://goo.gl/kyg8XX 👍 Facebook: https://goo.gl/L4e4fi 👥 Twitter: https://goo.gl/s9ScX9 ◆◇◈ 📧 Contact: valzzyy332@gmail.com

What Does a 4D Ball Look Like in Real Life? Amazing Experiment Shows Spherical Version of Tesseract

I show you what crazy stuff would happen if a 4th dimensional being were to move 4D objects through our 3D space. Weird things happen like the sudden appearing of objects, shape changing, sudden mirror imaging and more! This video is helpful to understanding a 4th spatial dimension using the simplest object...a sphere. This is easier than a tesseract to understand because it looks the same from all directions.

Click For Free Video: http://www.topspeedtennis.com/tennis-topspin-forehand-lower-body-movement/ Picking a Tennis Racket: The Truth Not Marketing (Part 1 of 4) If you are anything like me, you are sick and tired of all the marketing "hype" behind selling tennis rackets. Every year, the latest greatest racket is the fastest, most spinningest, laser controlled, racket that has ever been! By now we should all be hitting 500mph serves! So I decided to get behind the smoke and mirrors to take a deep dive into the real science of the tennis racket. What really creates power, spin and control. Once you truly understand the science behind the racket, you will be able to choose the perfect one for you. I look forward to working with you much more in the future with Top Speed Tennis. Good luck with your tennis.
