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 A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jumping
Jumping or leaping is a form of locomotion or movement in which an organism or non-living (e.g., robotic) mechanical system propels itself through the air along a ballistic trajectory. Jumping can be distinguished from running, galloping and other gaits where the entire body is temporarily airborne by the relatively long duration of the aerial phase and high angle of initial launch. Some animals, such as the kangaroo, employ jumping (commonly called ''hopping'' in this instance) as their primary form of an locomotion, while others, such as frogs, use it only as a means to escape predators. Jumping is also a key feature of various activities and sports, including the long jump, high jump and show jumping. Physics All jumping involves the application of force against a substrate, which in turn generates a reactive force that propels the jumper away from the substrate. Any solid or liquid capable of producing an opposing force can serve as a substrate, including ground or wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballet
Ballet () is a type of performance dance that originated during the Italian Renaissance in the fifteenth century and later developed into a concert dance form in France and Russia. It has since become a widespread and highly technical form of dance with Glossary of ballet, its own vocabulary. Ballet has been influential globally and has defined the foundational ballet technique, techniques which are used in many other dance genres and cultures. Various schools around the world have incorporated their own cultures. As a result, ballet has evolved in distinct ways. A ''ballet'' as a unified work of art, work comprises the choreography (dance), choreography and music for a ballet production. Ballets are choreographed and performed by trained ballet dancers. Traditional classical ballets are usually performed with classical music accompaniment and use elaborate costumes and staging, whereas modern ballets are often performed in simple costumes and without elaborate sets or scenery ...

Claude Balon
Claude Balon (also Ballon, often incorrectly named Jean; 1671–1744) was a French dancer and choreographer. He is listed as a performer in 11 known choreographies, with the earliest during the reign of King William III, and was credited as the deviser of 23 published choreographies, with the first appearing in 1714 The ballet term ballon is sometimes said to be derived from his name, but Robert Greskovic calls this "dubious". Balon danced under the tutelage of the balletmaster Pierre Beauchamp at the Paris Opera. Marie Sallé Marie Sallé (1707–1756) was a French dancer and choreographer in the 18th century known for her expressive, dramatic performances rather than a series of "leaps and frolics" typical of ballet of her time.

Laws Of Physics
Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. The term ''law'' has diverse usage in many cases (approximate, accurate, broad, or narrow) across all fields of natural science (physics, chemistry, astronomy, geoscience, biology). Laws are developed from data and can be further developed through mathematics; in all cases they are directly or indirectly based on empirical evidence. It is generally understood that they implicitly reflect, though they do not explicitly assert, causal relationships fundamental to reality, and are discovered rather than invented. Scientific laws summarize the results of experiments or observations, usually within a certain range of application. In general, the accuracy of a law does not change when a new theory of the relevant phenomenon is worked out, but rather the scope of the law's application, since the mathematics or statement representing t ...

Grand Jeté
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 partner ...

Center Of Mass
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weight function, weighted relative position (vector), position of the distributed mass sums to zero. For a rigid body containing its center of mass, this is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the Phys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballistic Trajectory
In physics, projectile motion describes the motion of an object that is launched into the air and moves under the influence of gravity alone, with air resistance neglected. In this idealized model, the object follows a parabolic path determined by its initial velocity and the constant acceleration due to gravity. The motion can be decomposed into horizontal and vertical components: the horizontal motion occurs at a constant velocity, while the vertical motion experiences uniform acceleration. This framework, which lies at the heart of classical mechanics, is fundamental to a wide range of applications—from engineering and ballistics to sports science and natural phenomena. Galileo Galilei showed that the trajectory of a given projectile is parabolic, but the path may also be straight in the special case when the object is thrown directly upward or downward. The study of such motions is called ballistics, and such a trajectory is described as ballistic. The only force of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Projectile
A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, they are commonly found in warfare and sports (for example, a thrown baseball, kicked football, fired bullet, shot arrow, stone released from catapult). In ballistics, mathematical equations of motion are used to analyze projectile trajectories through launch, flight, and impact. Motive force Blowguns and pneumatic rifles use compressed gases, while most other guns and cannons utilize expanding gases liberated by sudden chemical reactions by propellants like smokeless powder. Light-gas guns use a combination of these mechanisms. Railguns utilize electromagnetic fields to provide acceleration along the entire length of the device, greatly increasing the muzzle velocity. Some projectiles provide propulsion during flight by means of a rocket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ballet Technique
Ballet technique is the foundational principles of body movement and form used in ballet. It is an important aspect of ballet performance because ballet (especially classical ballet) puts great emphasis on the method and execution of movement., pp. 6-7 & 21. The techniques found in classical ballet are a framework for many other styles of dance, including jazz and contemporary ballet. Aspects of ballet technique include alignment, which refers to keeping the head, shoulders, and hips vertically aligned. Turnout refers to completing movements with legs rotated outward; this promotes clean footwork, graceful '' port de bras'' (movement of the arms), and correct body positions, lines and angles. Other aspects of ballet technique include posture, toe pointing, keeping shoulders down, and pulling up, which combines proper posture and lifting of the muscles to increase turnout and enhance alignment and thus improve the quality of turns. Ballet technique is also used to exhibit '' ballon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
