Dropping In
Dropping in is a skateboarding trick with which a skateboarder starts skating a half-pipe by dropping into it from the coping instead of starting from the bottom and pumping gradually for more speed.RIDE Channel. "Tony Hawk Teaches How to Drop-in on Vert./ref> When a skateboarder drops in, they use their gravitational energy, gravitational potential energy to gain initial velocity, allowing the skater to skate longer before exhausting themselves and thus to take more runs. When a skateboarder drops in, they stand on the deck of a half-pipe, put their back foot on the tail of the skateboard, and push it so that the back wheels just roll over the coping into a position like in a tail stall. They then put their front foot on the deck, which now hangs over the half-pipe, lean forward, and start skating the half-pipe.About.com http://skateboard.about.com/od/tricktips/ss/HowToDropIn.htm Gallery of skateboarders dropping in File:Bob_Burnquist_(7868976252).jpg, Bob Burnquist dropping ...

Skateboarding Trick
A skateboarding trick, or simply a trick, is a maneuver performed by manipulating a skateboard, usually with one's feet, in a specific way to achieve the desired outcome – the trick. History Though skateboards emerged in the 1900s, skateboarding tricks like the ones done today did not appear until decades later. In the 1970s and earlier, the most common tricks were "2D" freestyle types such as manuals and pivots. Only later in the 1980s and early 1990s were common modern-day tricks like the Ollie (skateboarding), ollie and heel-flip invented by Alan Gelfand and Rodney Mullen, setting the stage for other aerial tricks. The invention of these tricks changed the skateboarding lifestyle for many years to come. Types Ollie An ollie is a jump where the front wheels leave the ground first. This motion is attained with a snap of the tail (from the back foot) and sliding one's front foot forward to reach any altitude. A lot of technical tricks transpire from this element (e.g. the k ...

Half-pipe
A half-pipe is a structure used in gravity extreme sports such as skateboarding, snowboarding, skiing, freestyle BMX, skating, and scooter riding. Overview The structure resembles a cross-section of a swimming pool, essentially two concave ramps (or quarter-pipes), topped by copings and decks, facing each other across a flat transition, also known as a ''tranny''. Originally half-pipes were half sections of a large diameter pipe. Since the 1980s, half-pipes contain an extended ''flat bottom'' between the quarter-pipes. The original style half-pipes are no longer built. Flat ground provides time to regain balance after landing and more time to prepare for the next trick. Half-pipe applications include leisure recreation, skills development, competitive training, amateur and professional competition, demonstrations, and as an adjunct to other types of skills training. A skilled athlete can perform in a half-pipe for an extended period of time by pumping to attain extreme speeds wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pump (skateboarding)
Pumping is a skateboarding technique used to accelerate without the rider's feet leaving the board. Pumping can be done by turning or on a transition, like a ramp or quarter pipe.{{cite web , url=https://skateboarding.transworld.net/how-to/basics-ollies/pumping/ , title=Skateboarding 101: How to Pump on Transition and Maintain Speed , date=15 August 2024 When applied to longboards, it is also known as Long distance skateboard pumping or LDP. Pumping is a technique similar to pumping a surfboard. Transition Transition pumping can only be done when there is a slope differential between the front and rear wheels. On a ramp it therefore is only possible at the top and bottom of the slope, but in a pipe it is possible at any height above the flat. The rider should push downward on the truck with the greatest slope under the wheels. On the top of a ramp the front wheels should be pushed, and at the bottom the rear trucks should be pushed. On a pipe the weight should be applied ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravitational Energy
Gravitational energy or gravitational potential energy is the potential energy an object with mass has due to the gravitational potential of its position in a gravitational field. Mathematically, it is the minimum mechanical work that has to be done against the gravitational force to bring a mass from a chosen reference point (often an "infinite distance" from the mass generating the field) to some other point in the field, which is equal to the change in the kinetic energies of the objects as they fall towards each other. Gravitational potential energy increases when two objects are brought further apart and is converted to kinetic energy as they are allowed to fall towards each other. Formulation For two pairwise interacting point particles, the gravitational potential energy U is the work that an outside agent must do in order to quasi-statically bring the masses together (which is therefore, exactly opposite the work done by the gravitational field on the masses): U = -W_g = ...

Skateboard
A skateboard is a type of sports equipment used for skateboarding. It is usually made of a specially designed 7–8-ply maple plywood deck and has polyurethane wheels attached to the underside by a pair of skateboarding trucks. The skateboard moves by pushing with one foot while the other foot remains balanced on the board, or by Pump (skateboarding), pumping one's legs in structures such as a bowl or half pipe. A skateboard can also be used by standing on the deck while on a downward slope and allowing gravity to propel the board and the rider. If the rider's leading foot is their left foot, they are said to ride "regular". Conversely, they are said to ride "goofy" if their leading foot is their right foot. The two main types of skateboards are the longboard and shortboard. The shape of the board is also important: the skateboard must be concaved to perform tricks. History Skateboarding, as it exists today, was probably born sometime in the late 1940s, or early 1950s, when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bob Burnquist
Robert Dean Silva Burnquist (; born 10 October 1976) is a Brazilian-American professional skateboarder who competed for Brazil throughout his career. In 2010, he became the first skateboarder to land a " fakie 900" (900-degree reverse-natural rotation), making Burnquist the fifth person in history to successfully complete the 900 trick. Early life Burnquist was born in Rio de Janeiro, Brazil to parents Dean Riley Burnquist and Dora Silva. His father is American of Swedish descent, while his mother is Brazilian from Minas Gerais. He has two sisters, Rebecca and Milena. He began his skateboarding training in his hometown of São Paulo at 11 years old, and turned professional at 14. He holds dual citizenship in Brazil and the United States. Career Burnquist's specialties are switch stance skateboarding, and creating vert tricks. He has a signature trick called the "Wee Willy grind". In 2000, Burnquist won the X Games' best trick contest, with his famous Fakie 5–0 with ...

Mega Ramp
A mega ramp, or megaramp, is a large vert ramp structure, often used in skateboarding and freestyle BMX. First built in the 1990s and 2000s, megaramps are twice or more the size of earlier vert ramps. ''MegaRamp'' (styled with title caps and without a space) is the name of a mega ramp event organization and promotion company. Structure Contemporary structures are generally constructed of metal scaffold with a wood surface topped with Skatelite, and consist of two or three sections. The most common ramp setup, used as well by MegaRamp, is a sequence of three mega ramp sections; a roll-in, a gap jump, and a vert quarter pipe. Vert half-pipe mega ramps have been built, but they are uncommon. The roll-in section consists of a single or multiple roll-ins that drop from 12m (40') or higher up. The roll-in allows athletes to gain the speed needed to tackle the other sections of the ramp. The second section can be a quarter pipe, but is more often a gap jump with a distance of 7 ...

Bikini
A bikini is a two-piece swimsuit primarily worn by women that features one piece on top that covers the breasts, and a second piece on the bottom: the front covering the pelvis but usually exposing the navel, and the back generally covering the intergluteal cleft and some or all of the buttocks. The size of the top and bottom can vary, from bikinis that offer full coverage of the breasts, pelvis, and buttocks, to more revealing designs with a thong or G-string bottom that covers only the mons pubis, but exposes the buttocks, and a top that covers only the areolae. Bikini bottoms covering about half the buttocks may be described as "Brazilian-cut". The modern bikini swimsuit was introduced by French clothing designer Louis Réard in July 1946, and was named after the Bikini Atoll, where the first public test of a nuclear bomb had taken place four days before. Due to its revealing design, the bikini was once considered controversial, facing opposition from a number of grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
