Split Leap
A split leap or split jump is a sequence of body movements in which a person assumes a split position after leaping or jumping from the floor, respectively, while still in the air. Split leaps and split jumps are both found in various genres of dance including acro, ballet and jazz dance, and in gymnastics. Split jumps may also serve as a form of exercise, and the term ''split jump'' is also commonly used to describe similar body movements in figure skating. __TOC__ Types Some types of split leaps and jumps are named according to the type of split that is performed, while others may use nomenclature associated with specific dance genres. For example, a ''straddle'' (sometimes called ''side'') split leap incorporates a straddle split, with legs extended symmetrically to the sides, whereas a grand jeté, which involves a front split, derives its name from ballet terminology. A ''stag split leap'' is a split leap in which one knee is bent, whereas both knees are bent in a ''double ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Momentum
In Newtonian mechanics, momentum (more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. If is an object's mass and is its velocity (also a vector quantity), then the object's momentum is : \mathbf = m \mathbf. In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second. Newton's second law of motion states that the rate of change of a body's momentum is equal to the net force acting on it. Momentum depends on the frame of reference, but in any inertial frame it is a ''conserved'' quantity, meaning that if a closed system is not affected by external forces, its total linear momentum does not change. Momentum is also conserved in special relativity (with a modified formula) and, in a modified form, in electrodynamics, quantum mechanics, quan ...

Split Jump
A split jump is a sequence of body movements in which a split is performed after jumping, while the performer is still in the air. Split jumps are commonly found in dance, figure skating, and gymnastics, and may also be used as a form of exercise. In figure skating Split jumps are a category of figure skating jumps in which the skater achieves a split position in the air. Unlike most figure skating jumps, split jumps are positional jumps, rather than rotational jumps; the point of them is to achieve a position in the air, not to rotate a specific number of times. Most split jumps are derived from the half flip, a half-rotation jump with a flip entry. Split jumps can also be done with half Lutz or falling leaf (a loop jump with a half-revolution in the air) entries. More rarely, full-rotation flip and Lutz jumps can be done with a split. These jumps are known as the ''split flip'' and ''split Lutz''. As an alternative to the standard front split, some skaters perform a ''Russia ...

Bolshoi Ballet
The Bolshoi Ballet is an internationally renowned classical ballet company based at the Bolshoi Theatre in Moscow, Russia. Founded in 1776, the Bolshoi is among the world's oldest ballet companies. In the early 20th century, it came to international prominence as Moscow became the capital of Soviet Russia. The Bolshoi has been recognised as one of the foremost ballet companies in the world. It has a branch at the Bolshoi Ballet Theater School in Joinville, Brazil. History The earliest iteration of the Bolshoi Ballet can be found in the creation of a dance school for a Moscow orphanage in 1773. In 1776, dancers from the school were employed by Prince Pyotr Vasilyevich Urusov and English theatrical entrepreneur Michael Maddox to form part of their new theatre company. Originally performing in privately owned venues, they later acquired the Petrovsky Theatre, which, as a result of fires and erratic redevelopment, would later be rebuilt as today's Bolshoi Theatre.

Battement
In ballet, battement () is an alternating side-to-side movement of the working (non-supporting) leg. Battements are typically performed in multiples, quickly and in rapid succession so that the working foot appears to be fluttering or vibrating. They are usually executed in front (''en avant'' or ''à la quatrieme devant''), to the side (''à la seconde'') or in back (''en arrière'' or ''à la quatrieme derrière''). The word ''battement'' is of French origin, meaning "beat". Variations Battements are performed or executed in a variety of modes or configurations, for example: * battement développé is usually a slow ''battement'' in which the leg is first lifted to ''retiré'' position, then fully extended (or "unfolded") passing through ''attitude'' position. *battement fondu is a ''battement'' (usually slower) from '' fondu'' (both knees bent, working foot on the ''cou-de-pied'' of the supporting leg) position and extends until both legs are straight. Upon completion, the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballet Terminology
Because ballet became formalized in France, a significant part of ballet terminology is in the French language. A À la seconde () (Literally "to second") If a step is done "à la seconde," it is done to the side. 'Second position'. It can also be a balance extending one foot off the ground in ‘Second Position’. À la quatrième () One of the directions of body, facing the audience (''en face''), arms in second position, with one leg extended either to fourth position in front (''quatrième devant'') or fourth position behind (''quatrième derrière''). À terre () Touching the floor; on the floor. Adagio Italian, or French ''adage'', meaning 'slowly, at ease.' # Slow movements performed with fluidity and grace. # One of the typical exercises of a traditional ballet class, done both at barre and in center, featuring slow, controlled movements. # The section of a '' grand pas'' (e.g., '' grand pas de deux''), often referred to as ''grand adage'', that features dance part ...

Ballon (ballet)
Ballon () is the appearance of being lightweight and light-footed while jumping. It is a desirable aesthetic in ballet and other dance genres, making it seem as though a dancer effortlessly becomes airborne, floats in the air, and lands softly. The name is widely thought to be derived from the French word ''ballon'' (meaning "balloon"), though it has been dubiously claimed that the name was inspired by French ballet danseur Claude Balon, who was known for performing exceptionally light leaps. Physics A dancer will appear to defy the laws of physics when ballon is exhibited effectively. For example, during a grand jeté, the dancer may appear to hover in the air. Physically, the dancer's center of mass follows a ballistic trajectory, as does any projectile, but observers have limited ability to reckon center of mass when a projectile changes its configuration in flight. By raising the arms and legs while ascending and lowering them while descending, the dancer alters the apparent pat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apex (geometry)
In geometry, an apex (plural apices) is the vertex which is in some sense the "highest" of the figure to which it belongs. The term is typically used to refer to the vertex opposite from some " base". The word is derived from the Latin for 'summit, peak, tip, top, extreme end'. Isosceles triangles In an isosceles triangle In geometry, an isosceles triangle () is a triangle that has two sides of equal length. Sometimes it is specified as having ''exactly'' two sides of equal length, and sometimes as having ''at least'' two sides of equal length, the latter versio ..., the apex is the vertex where the two sides of equal length meet, opposite the unequal third side. Pyramids and cones In a Pyramid (geometry), pyramid or Cone (geometry), cone, the apex is the vertex at the "top" (opposite the base). In a pyramid, the vertex is the point that is part of all the lateral faces, or where all the lateral edges meet. References {{elementary-geometry-stub Parts of a triangle ...

Best Practice
A best practice is a method or technique that has been generally accepted as superior to other known alternatives because it often produces results that are superior to those achieved by other means or because it has become a standard way of doing things, e.g., a standard way of complying with legal or ethical requirements. Best practices are used to maintain quality as an alternative to mandatory legislated standards and can be based on self-assessment or benchmarking. Best practice is a feature of accredited management standards such as ISO 9000 and ISO 14001. Some consulting firms specialize in the area of best practice and offer ready-made templates to standardize business process documentation. Sometimes a best practice is not applicable or is inappropriate for a particular organization's needs. A key strategic talent required when applying best practice to organizations is the ability to balance the unique qualities of an organization with the practices that it has in common ...

Kinetic Energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. Formally, a kinetic energy is any term in a system's Lagrangian which includes a derivative with respect to time. In classical mechanics, the kinetic energy of a non-rotating object of mass ''m'' traveling at a speed ''v'' is \fracmv^2. In relativistic mechanics, this is a good approximation only when ''v'' is much less than the speed of light. The standard unit of kinetic energy is the joule, while the English unit of kinetic energy is the foot-pound.
