Golf Simulator
Indoor golf is an umbrella term for all activities in golf which can be carried out indoors. Venues include indoor driving ranges, chipping areas, putting greens, machines and home golf simulators. Many of these indoor facilities are businesses that include additional entertainment options as well as food and drink for customers. A golf simulator allows golf to be played on a graphically or photographically simulated driving range or golf course, usually in an indoor setting. In some cases, based on the location of the sensing devices, it is now possible to capture data on both ball and club for most accurate speed and directional information, and simulated ball flight behavior. The data about a golfers swing that is collected during a golf shot is extrapolated to provide ball flight trajectory and roll out according to certain calculated relationships to the ball's flight performance per the tracked motion of the ball or club, adding environmental aspects through which the ball ...

Velocity
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. northbound). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called , being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object is said to be undergoing an ''acceleration''. Constant velocity vs acceleration To have a ''constant velocity'', an object must have a constant speed in a constant direction. Constant direction cons ...

Country Club
A country club is a privately owned club, often with a membership quota and admittance by invitation or sponsorship, that generally offers both a variety of recreational sports and facilities for dining and entertaining. Typical athletic offerings are golf, tennis, and swimming. Where golf is the principal or sole sporting activity, and especially outside of the United States and Canada, it is common for a country club to be referred to simply as a golf club. Country clubs are most commonly located in city outskirts or suburbs, due to the requirement of having substantial grounds for outdoor activities, which distinguishes them from an urban athletic club. Country clubs originated in Scotland and first appeared in the US in the early 1880s.Simon, Roger D. “Country Clubs.” In The Encyclopedia of American Urban History, edited by David R.

Hazard (golf)
A hazard is an area of a golf course in the sport of golf which provides a difficult obstacle, which may be of two types: (1) water hazards such as lakes and rivers; and (2) man-made hazards such as bunkers. The governing body for the game of golf outside the US and Canada, The R&A, say that ''A "hazard" is any bunker or water hazard''. Special rules apply to play balls that fall in a hazard. For example, a player may not touch the ground with their club before playing a ball, not even for a practice swing. A ball in any hazard may be played as it lies without penalty. If it cannot be played from the hazard, the ball may be hit from another location, generally with a penalty of one stroke. The Rules of Golf govern exactly from where the ball may be played outside a hazard. Bunkers (or sand traps) are shallow pits filled with sand and generally incorporating a raised lip or barrier, from which the ball is more difficult to play than from grass. Bunker A bunker is a depression n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golf Course
A golf course is the grounds on which the sport of golf is played. It consists of a series of holes, each consisting of a tee box, a fairway, the rough and other hazards, and a green with a cylindrical hole in the ground, known as a "cup". The cup holds a flagstick, known as a "pin". A standard round of golf consists of 18 holes, and as such most courses contain 18 distinct holes; however, there are many 9-hole courses and some that have holes with shared fairways or greens. There are also courses with a non-standard number of holes, such as 12 or 14. The vast majority of golf courses have holes of varying length and difficulties that are assigned a standard score, known as par, that a proficient player should be able to achieve; this is usually three, four or five strokes. Par-3 courses consist of holes all of which have a par of three. Short courses have gained in popularity; these consist of mostly par 3 holes, but often have some short par 4 holes. Many older courses ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-supported Structure
An air-supported (or air-inflated) structure is any building that derives its structural integrity from the use of internal pressurized air to inflate a pliable material (i.e. structural fabric) envelope, so that air is the main support of the structure, and where access is via airlocks. The first air-supported structure built in history was the radome manufactured at the Cornell Aeronautical Laboratory in 1948 by Walter Bird. The concept was implemented on a large scale by David H. Geiger with the United States pavilion at Expo '70 in Osaka, Japan in 1970. It is usually dome-shaped, since this shape creates the greatest volume for the least amount of material. To maintain structural integrity, the structure must be pressurized such that the internal pressure equals or exceeds any external pressure being applied to the structure (i.e. wind pressure). The structure does not have to be airtight to retain structural integrity—as long as the pressurization system that supplies in ...

12 Foot Indoor Golf Green
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light which is ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of ligh ...

Golf
Golf is a club-and-ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible. Golf, unlike most ball games, cannot and does not use a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game. Courses typically have either 18 or 9 ''holes'', regions of terrain that each contain a ''cup'', the hole that receives the ball. Each hole on a course contains a teeing ground to start from, and a putting green containing the cup. There are several standard forms of terrain between the tee and the green, such as the fairway, rough (tall grass), and various ''hazards'' such as water, rocks, or sand-filled ''bunkers''. Each hole on a course is unique in its specific layout. Golf is played for the lowest number of strokes by an individual, known as stroke play, or the lowest score on the most individual holes in a complete round by an individual or team, k ...

Wavelength
In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. It is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero crossings, and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. The inverse of the wavelength is called the spatial frequency. Wavelength is commonly designated by the Greek letter ''lambda'' (λ). The term ''wavelength'' is also sometimes applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids. Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Wavelength depends on the medium (for example, vacuum, air, or water) that a wav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TrackMan
The TrackMan is a radar system that uses Doppler technology to track and record 3D characteristics of a sports ball in motion. History TrackMan was created in 2003 by golfers Klaus (CEO) and Morten Eldrup-Jørgensen and radar engineer Fredrik Tuxen ( CTO). Tuxen worked with the tracking of bullets and missiles using Doppler radar. The Jorgensen brothers contacted him to see if the technology could be used to track golf balls. The team developed the TrackMan system and demonstrated it in the United States to five golf manufacturers. Mizuno, Nike, Ping, Callaway, and TaylorMade became TrackMan's first customers. TrackMan products are sold worldwide to professionals, amateurs, and businesses. The company's headquarters is in Vedbæk, Denmark. Usage Golf The TrackMan is a device that uses Doppler radar to monitor the launch of a golf ball. It is set up behind the golfer and is roughly the size of a laptop. With each swing, it measures every aspect of the club movement, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
