==1. Know the 10 simple rules of Ultimate and how the game is played.==
 
;The Field: A rectangular shape with end zones at each end. A regulation field is 70 yards by 40 yards, with end zones 25 yards deep.
 
;Initiate Play: Each point begins with both teams lining up on the front of their respective end zone line. The defense throws ("pulls") the disc to the offense. A regulation game has seven players per team.
 
;Scoring: Each time the offense completes a pass in the defense's end zone, the offense scores a point. Play is initiated after each score.
 
;Movement of the Disc: The disc may be advanced in any direction by completing a pass to a teammate. Players may not run with the disc. The person with the disc ("thrower") has ten seconds to throw the disc. The defender guarding the thrower ("marker") counts out the stall count.
 
;Change of Possession: When a pass is not completed (e.g. out of bounds, drop, block, interception), the defense immediately takes possession of the disc and becomes the offense.
 
;Substitutions: Players not in the game may replace players in the game after a score and during an injury timeout.
 
;Non-contact: No physical contact is allowed between players. Picks and screens are also prohibited. A foul occurs when contact is made.
 
;Fouls: When a player initiates contact on another player a foul occurs. When a foul disrupts possession, the play resumes as if the possession was retained. If the player committing the foul disagrees with the foul call, the play is redone.
 
;Self-Officiating: Players are responsible for their own foul and line calls. Players resolve their own disputes.
 
;Spirit of the Game: Ultimate stresses sportsmanship and fair play. Competitive play is encouraged, but never at the expense of respect between players, adherence to the rules, and the basic joy of play

'''Flying discs''' (commonly called '''frisbees''') are disc-shaped gliders, which are generally [[plastic]] and roughly 20 to 25 centimeters (8–10&nbsp;inches) in [[diameter]], with a lip. The shape of the disc, an [[airfoil]] in cross-section, allows it to [[flight|fly]] by generating [[lift (force)|lift]] as it moves through the air while rotating. The name Frisbee is a registered [[trademark]] of the [[Wham-O]] toy company, but is often used uncapitalized [[genericized trademark|generically]] to describe all flying discs.  
The term Frisbee, often used capitalized, to generically describe all flying discs, is a registered trademark of the Wham-O toy company. Though such use is not encouraged by the company, the common use of the name as a generic term has put the trademark in jeopardy; accordingly, many "Frisbee" games are now known as "ultimate" or "disc" games.
 
  
==4. Identify and be able to throw the disk:==
+
Flying discs are thrown and caught for [[recreation]], and as part of many different [[flying disc games]]. A wide range of flying disc variants are available commercially. [[Disc golf]] discs are usually smaller but denser and are tailored for particular flight profiles to increase/decrease stability and distance. [[Disc dog]] sports use relatively slow flying discs made of more pliable material to better resist a dog's bite and prevent injury to the dogRing shaped discs are also available which typically fly significantly farther than any traditional flying discThere are illuminated discs meant for night time play that use [[Phosphorescence|phosphorescent]] plastic, or  battery powered [[light-emitting diode|light emitting diodes]]. There are also discs that whistle when they reach a certain velocity in flight.

In 1955, Morrison produced a new plastic flying disc called the '''Pluto Platter''', to cash in on the growing popularity of [[UFO]]s with the American public. The Pluto Platter became the design basis for later flying discs. In 1957, [[Wham-O]] began production of more discs (then still marketed as Pluto Platters).

Depending on the cross-sectional shape of the airfoil, the amount of lift generated by the front and back parts of the disc may be unequal. If the disc were not spinning, this would tend to make it [[Flight dynamics|pitch]]. When the disc is spinning, however, such a torque would cause it to [[precession|precess]] about the roll axis, causing its trajectory to curve to the left or the right. Most discs are designed to be aerodynamically stable, so that this roll is self-correcting for a fairly broad range of velocities and rates of spin. However, many [[disc golf]] discs are intentionally designed to be unstable. Higher rates of spin lead to better stability, and for a given rate of spin, there is generally a range of velocities that are stable.

Even a slight deformation in a disc (called a "Taco," as extreme cases look like a [[taco shell]]) can cause adverse affects when throwing long range. It can be observed by holding the disc horizontally at eye level and looking at the rim while slowly rotating the disc.

A person catching a flying disc

Flying discs (commonly called frisbees) are disc-shaped gliders, which are generally plastic and roughly 20 to 25 centimeters (8–10 inches) in diameter, with a lip. The shape of the disc, an airfoil in cross-section, allows it to fly by generating lift as it moves through the air while rotating. The name Frisbee is a registered trademark of the Wham-O toy company, but is often used uncapitalized generically to describe all flying discs.

Flying discs are thrown and caught for recreation, and as part of many different flying disc games. A wide range of flying disc variants are available commercially. Disc golf discs are usually smaller but denser and are tailored for particular flight profiles to increase/decrease stability and distance. Disc dog sports use relatively slow flying discs made of more pliable material to better resist a dog's bite and prevent injury to the dog. Ring shaped discs are also available which typically fly significantly farther than any traditional flying disc. There are illuminated discs meant for night time play that use phosphorescent plastic, or battery powered light emitting diodes. There are also discs that whistle when they reach a certain velocity in flight.

History

The clay target used in trapshooting, almost identical to a flying disc in shape, was designed in the 19th century. A

The modern day era of flying discs began with the concept of designing and selling a commercially produced flying disc.& In 1946 Walter Frederick Morrison sketched out plans for a disc he called the Whirlo-Way, which, co-developed and financed by Warren Franscioni in 1948, became the very first commercially produced plastic flying disc, marketed under the name Flyin-Saucer. Morrison had just returned to the US after World War II, where he had been a prisoner of war. His partnership with Franscioni, who was also a war veteran, ended in 1950, before their product had achieved any real success.

In 1955, Morrison produced a new plastic flying disc called the Pluto Platter, to cash in on the growing popularity of UFOs with the American public. The Pluto Platter became the design basis for later flying discs. In 1957, Wham-O began production of more discs (then still marketed as Pluto Platters). The next year, Morrison was awarded US Design Patent 183,626 for his flying disc.

In 1957,& Wham-O co-founder Richard Knerr, decided to stimulate sales by giving the discs the additional brand name "Frisbee" (pronounced "FRIZ'-bee"), after hearing that East Coast college students were calling the Pluto Platter by that name. The man who was behind the Frisbee's phenomenal success however was "Steady" Ed Headrick, hired in 1964 as Wham-O's new General Manager and Vice President in charge of marketing. Headrick soon redesigned the Pluto Platter by reworking the rim thickness, and top design, creating a more controllable disc that could be thrown accurately. &

Sales soared for the toy, which was marketed as a new sport. In 1964, the first "professional" model went on sale. Headrick patented the new design as the Frisbee patent, highlighting the “Rings of Headrick” and marketed and pushed the professional model Frisbee and "Frisbee" as a sport. (US Patent 3,359,678).&

Headrick, commonly known as the "Father of Disc Sports",& later founded "The International Frisbee Association (IFA)" and began establishing standards for various sports using the Frisbee such as Distance, Freestyle and Guts. Upon his death Headrick was cremated and, in accordance with his final requests, his ashes were molded into memorial Frisbees and given to family and close friends.&
