Football is a family of sports that involve kicking a ball with the foot to score a goal.
Bond triangles or van Arkel–Ketelaar triangles (named after Anton Eduard van Arkel and J. A. A. Ketelaar) are triangles used to show different compounds in varying degrees of ionic, metallic and covalent bonding.
 The bond triangle shows that ionic, metallic and covalent bonds are not just particular bonds of a specific type.
 Rather, bond types are interconnected and different compounds have varying degrees of different bonding character (for example, covalent bonds with significant ionic character are called polar covalent bonds).
A kickoff is a method of starting a drive in American football and Canadian football.
 Typically, a kickoff consists of one team – the "kicking team" – kicking the ball to the opposing team – the "receiving team".
 The receiving team is then entitled to "return" the ball, i.e., attempt to advance it towards the kicking team's end zone, until the player with the ball is tackled by the kicking team, goes out of bounds, or scores a touchdown.
 Kickoffs take place at the start of each half of play, the beginning of overtime in some overtime formats, and after some scoring plays.
A Virtual Military Organization (VMO) is a dedicated hobby organization that uses simulation to model the operations of a military.
 Virtual Military Organizations (VMOs) generally have a presence on the internet, similar to real military organizations.
 Most VMOs simulate military operations to varying degrees.
 A newer variant of Virtual Military is the MilSim unit.
 MilSim units differ from Virtual Military by placing emphasis on the simulation of military tactics in their chosen gaming platform, whereas traditionally, VMOs have placed emphasis on simulating the bigger picture, including a full military career path, logistics systems, coordinated movement of equipment around the world, and prolonged military operations.
 Although VMOs may appear to be a type of gaming clan, a key difference is that a gaming clan's primary purpose is to be an "organized group of players that regularly play together."
 VMOs are essentially role-playing environments within which an individual can immerse themselves.
 "Realism" groups are semantically similar; however, their primary focus is usually on following real-life procedures as much as possible.
 Therefore, tactical realism and MilSim are almost synonymous in the gaming world.
 A Google search for 'Virtual Military' reveals quite a few VMOs that go to varying degrees of depth to pursue their goal.
In the sport of Australian rules football, a kick-in (sometimes known as a kick-out) occurs when an opposition team scores a behind, with a defender kicking the ball out from the defensive goalsquare.
 The team kicking in may elect any one of its players to take the kick-in.
 The man on the mark stands five metres in front of the goal square.
 The player kicking in is given approximately ten to fifteen seconds from when they pick up the ball to take their kick before the umpire will call play-on, at which point the man on the mark may advance.
 Players kicking in may either kick to a teammate, or kick to themselves to allow themselves to play on.
 Whichever option is taken, the player must kick from wholly within the white lines of the goal square, even if the umpire has already called play-on for taking too much time - if their foot touches the line of the goal square, then play is stopped and the umpire will bounce the ball at the centre of the kick-off line.
In ball-playing competitive team sports, an interception or pick is a move by a player involving a pass of the ball—whether by foot or hand, depending on the rules of the sport—in which the ball is intended for a player of the same team but caught by a player of the opposing team, who thereby usually gains possession of the ball for their team.
 It is commonly seen in football, including Canadian and American football, as well as association football, rugby league, rugby union, Australian rules football and Gaelic football, as well as any sport in which a loose object is passed between players toward a goal, including ice hockey, field hockey, basketball and lacrosse.
Football is a family of team sports that involve, to varying degrees, kicking a ball with the foot to score a goal.
 Unqualified, the word "football" is understood to refer to whichever form of football is the most popular in the regional context in which the word appears.
 Sports commonly called 'football' in certain places include: association football (known as soccer in some countries); gridiron football (specifically American football or Canadian football); Australian rules football; rugby football (either rugby league or rugby union); and Gaelic football.
 These different variations of football are known as football codes.
Dandy–Walker syndrome (DWS) is a rare group of congenital human brain malformations.
 There are three subtypes which affect multiple organs to varying degrees, but the fundamental abnormalities involve the cerebellum which controls muscle coordination.
 The adjacent fourth ventricle is often affected, which can alter the flow of cerebrospinal fluid, increase intracranial pressure, and lead to multiple other brain function problems.
 The degree of disability varies but is typically lifelong.
 Treatment may involve physical therapy, special education, or surgical placement of a cerebral shunt.
 It is named for Walter Dandy and Arthur Earl Walker.
 In the majority of individuals with Dandy–Walker malformation, signs and symptoms caused by abnormal brain development are present at birth or develop within the first year of life.
 Some children have a buildup of fluid in the brain (hydrocephalus) that may cause increased head size (macrocephaly).
 Up to half of affected individuals have intellectual disability that ranges from mild to severe, and those with normal intelligence may have learning disabilities.
 Children with Dandy–Walker malformation often have delayed development, particularly a delay in motor skills such as crawling, walking, and coordinating movements.
 People with Dandy–Walker malformation may experience muscle stiffness and partial paralysis of the lower limbs (spastic paraplegia), and they may also have seizures.
 While rare, hearing and vision problems can be features of this condition.

Roll ball or rollball is a sport similar to basketball or handball that is played on inline roller skates.
 The play consists of two teams of six players each, five field players and a goal tender.

 The team that is able to score more goals wins.
 There are two referees in a match.
 The ball can be held in either one or both the hands, even during passing and shooting.
