Seam Bowling
Seam bowling is a bowling technique in cricket whereby the ball is deliberately bowled on to its seam, to cause a random deviation when the ball bounces. Practitioners are known as ''seam bowlers'' or seamers. Seam bowling is generally classed as a subtype of fast bowling, although the bowling speeds at which seam can be a factor include medium-pace bowling. Although there are specialist seamers that make deliberate use of off cutter and leg cutter at the expense of bowling slower than regular fast bowlers, most bowlers employ the seam to some effect and so the terms "seamer" and "fast bowler" are largely synonymous. This was far less the case in the past, even the recent past. Bowlers such as Tom Cartwright and Derek Shackleton bowled seamers at a pace in the low 70mphs and were very successful due to their mastery of control and variation. Physics A cricket ball is not a perfect sphere. The seam of the ball is the circular stitching which joins the two halves of the cricket ba ...

Bowling (cricket)
Bowling, in cricket, is the action of propelling the ball toward the wicket defended by a batter. A player skilled at bowling is called a ''bowler''; a bowler who is also a competent batter is known as an all-rounder. Bowling the ball is distinguished from ''throwing'' the ball by a strictly specified biomechanical definition, which restricts the angle of extension of the elbow. A single act of bowling the ball towards the batsman is called a ''ball'' or a '' delivery''. Bowlers bowl deliveries in sets of six, called an ''over''. Once a bowler has bowled an over, a teammate will bowl an over from the other end of the pitch. The Laws of Cricket govern how a ball must be bowled. If a ball is bowled illegally, an umpire will rule it a ''no-ball''. If a ball is bowled too wide of the striker for the batsman to be able to play at it with a proper cricket shot, the bowler's end umpire will rule it a ''wide''. There are different types of bowlers, from fast bowlers, whose primary w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gyroscope
A gyroscope (from Ancient Greek γῦρος ''gŷros'', "round" and σκοπέω ''skopéō'', "to look") is a device used for measuring or maintaining orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum. Gyroscopes based on other operating principles also exist, such as the microchip-packaged MEMS gyroscopes found in electronic devices (sometimes called gyrometers), solid-state ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope. Applications of gyroscopes include inertial navigation systems, such as in the Hubble Space Telescope, or inside the steel hull of a submerged submarine. Due to their precision, gyroscopes are also used in gyrotheodolites to maintain direction in tunnel mining. Gyroscopes ca ...

Precession
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, if the axis of rotation of a body is itself rotating about a second axis, that body is said to be precessing about the second axis. A motion in which the second Euler angle changes is called ''nutation''. In physics, there are two types of precession: torque-free and torque-induced. In astronomy, ''precession'' refers to any of several slow changes in an astronomical body's rotational or orbital parameters. An important example is the steady change in the orientation of the axis of rotation of the Earth, known as the precession of the equinoxes. Torque-free Torque-free precession implies that no external moment (torque) is applied to the body. In torque-free precession, the angular momentum is a constant, but the angular velocit ...

Innings
An innings is one of the divisions of a cricket match during which one team takes its turn to bat. Innings also means the period in which an individual player bats (acts as either striker or nonstriker). Innings, in cricket, and rounders, is both singular and plural; this contrasts with baseball and softball in which the singular is "inning". Origin The earliest known record of the term concerns a match in August 1730 at Blackheath, Kent between a Kent side and London Cricket Club. The London-based ''St. James Evening Post'' reported: "'Twas thought that the Kentish champions would have lost their honours by being beat at one innings if time had permitted". Usage in cricket An innings is one of the divisions of a match during which one team takes its turn to bat, and is said to be "in to bat". Innings is the subject of Law 13 in the ''Laws of Cricket''. * In a first-class match, there are up to four innings with each team due to bat twice (in practice, this is not always the c ...

Swing Bowling
Swing bowling is a technique used for bowling in the sport of cricket. Practitioners are known as swing bowlers. Swing bowling is generally classed as a subtype of fast bowling. The aim of swing bowling is to cause the ball to move in the air (or 'swing') whilst delivering mainly fast-paced balls to the batsman, in the hope that the change in the ball's flight path will deceive the batsman and cause them to play the ball incorrectly. Swing bowling is not to be confused with spin bowling, which involves bowling slow-pace balls which change direction primarily after making contact with the ground. Swing bowling involves the use of a newer ball which is only slightly worn. The bowling side will continually polish one side of the ball by applying saliva and sweat to it as well as rubbing it against their clothing to shine it, whilst leaving the opposite side unshined. The speed of airflow over the rough and smooth sides of the ball will cause the ball to move in flight towards th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fielding Positions In Cricket
Fielding in the sport of cricket is the action of fielders in collecting the cricket ball, ball after it is struck by the Batting (cricket), striking batter, to limit the number of run (cricket), runs that the striker scores and/or to get a batter Dismissal (cricket), out by either Catch (cricket), catching a hit ball before it bounces, or by Run out, running out either batter before they can complete the run they are currently attempting. There are a number of recognised fielding positions, and they can be categorised into the Off side, offside and leg side of the field. Fielding also involves preventing the ball from going to or over the edge of the field (which would result in runs being scored by the batting team in the form of a boundary (cricket)#Scoring runs, boundary). A ''fielder'' or ''fieldsman'' may field the ball with any part of his body. However, if while the ball is in play he wilfully fields it otherwise (e.g. by using his hat), the ball becomes Dead ball (c ...

Cricket Bat
A cricket bat is a specialised piece of equipment used by batters in the sport of cricket to hit the ball, typically consisting of a cane handle attached to a flat-fronted willow-wood blade. It may also be used by a batter who is making ground to avoid a run out, by holding the bat and touching the ground with it. The length of the bat may be no more than 38 inches (96.5 cm) and the width no more than 4.25 inches (10.8 cm). Its use is first mentioned in 1624. Since 1979, a law change has provided that cricket bats can only be made from wood. Construction The ''blade'' of a cricket bat is a wooden block that is generally flat on the striking face and with a ridge on the reverse (back) which concentrates wood in the middle where the ball is generally hit. The bat is traditionally made from willow wood, specifically from a variety of white willow called cricket bat willow (''Salix alba'' var. ''caerulea''), treated with raw (unboiled) linseed oil, which has a protecti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
