2000 (breakdance Move)
The 2000 is a B-boying move which resembles a rapidly spinning handstand. It is a type of spin in practice, but many consider it a power move because it is so flashy and is often begun with significant momentum like other power moves. As one might guess from the name, the 2000 developed soon after the 1990, and it is the most recognized variant of its predecessor. The difference between the two is that in the 2000, the non-spinning hand is lifted and placed directly on top of the spinning hand rather than pulled away from the ground (as in the 1990). The rotations appear more symmetrical than 1990s. It is relatively easier in terms of strength than the 1990 because two hands are stronger than one, but it is equally difficult to maintain balance because the body should spin along a perfectly vertical axis. The fastest spins are achieved by beginning with the legs in a wide-open initial position and snapping them closed once the spin begins. This causes a dramatic reduction in rotat ...

B-boying
Breakdancing, also called breaking or b-boying/b-girling, is an athletic style of street dance originating from the African American and Puerto Rican communities in the United States. While diverse in the amount of variation available in the dance, breakdancing mainly consists of four kinds of movement: toprock, downrock, power moves and freezes. Breakdancing is typically set to songs containing drum breaks, especially in hip-hop, funk, soul music and breakbeat music, although modern trends allow for much wider varieties of music along certain ranges of tempo and beat patterns. The modern dance elements of breakdancing originated among the poor youth of New York during the early 1970s, where it was introduced as breaking. It is closely attributed to the birth of hip-hop, as DJs developed rhythmic breaks for dancers. The dance form has since expanded globally, with an array of organizations and independent competitions supporting its growth. Breaking will now be featured as ...

Handstand
__NOTOC__ A handstand is the act of supporting the body in a stable, inverted vertical position by balancing on the hands. In a basic handstand, the body is held straight with arms and legs fully extended, with hands spaced approximately shoulder-width apart and the legs together. There are many variations of handstands, all of which require the performer to possess adequate balance and upper body strength. Kinematics Handstands use the wrist flexor muscles as well as the anterior deltoid, pectoralis major, latissimus dorsi, biceps brachii, and trapezius descendens. It is considered demanding in terms of both the muscle and joint requirement. According to a 2017 study most handbalancers use wrist movement to maintain balance in a handstand. Another study found that handbalancers who were also expert gymnasts had better coordination than those at an intermediate level of gymnastics. More advanced practitioners also altered their center of pressure less to change the center of mas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spin (B-boying Move)
Spin or spinning most often refers to: * Spinning (textiles), the creation of yarn or thread by twisting fibers together, traditionally by hand spinning * Spin, the rotation of an object around a central axis * Spin (propaganda), an intentionally biased portrayal of something Spin, spinning or spinnin may also refer to: Physics and mathematics * Spin, the rotation of an object around a central axis * Spin (physics) or particle spin, a fundamental property of elementary particles * Spin group, a particular double cover of the special orthogonal group SO(''n'') * Spin tensor, a tensor quantity for describing spinning motion in special relativity and general relativity * Spin (aerodynamics), autorotation of an aerodynamically stalled aeroplane * SPIN bibliographic database, an indexing and abstracting service focusing on physics research Textile arts * Spinning (polymers), a process for creating polymer fibres * Spinning (textiles), the creation of yarn or thread by twisting fibe ...

Power Moves
Power moves are dance moves which are loosely defined as moves relying on speed, momentum, and acrobatic elements for performance. They are prominent in B-boying, often the centerpieces of routines featuring the other elements (toprock, downrock, and freezes) that make up breaking. Power moves are closer to gymnastics than dancing. B-boys who focus heavily on power moves and execute them as a main part of their routines are often called "power heads". Origin B-boy Powerful PEX and the New York City Breakers were credited in 1983 for the B-boy style of combining 2 or 3 difficult moves together. This includes floats, Headmills aka Power windmills, and flares suicides. In the 1990s the B-boys shortened the phrase "powerful moves" down to "power moves" in the 1990s to make it sound more flashy. New generations of B-boys are executing more acrobatics, which is taking moves to the next level. Types Spins *Back spin: One of the first and most famous spinning power moves, the dancer ...

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 ...

Axis Of Rotation
Rotation around a fixed axis is a special case of rotational motion. The fixed-axis hypothesis excludes the possibility of an axis changing its orientation and cannot describe such phenomena as wobbling or precession. According to Euler's rotation theorem, simultaneous rotation along a number of stationary axes at the same time is impossible; if two rotations are forced at the same time, a new axis of rotation will appear. This article assumes that the rotation is also stable, such that no torque is required to keep it going. The kinematics and dynamics of rotation around a fixed axis of a rigid body are mathematically much simpler than those for free rotation of a rigid body; they are entirely analogous to those of linear motion along a single fixed direction, which is not true for ''free rotation of a rigid body''. The expressions for the kinetic energy of the object, and for the forces on the parts of the object, are also simpler for rotation around a fixed axis, than for ...

Rotational Inertia
The moment of inertia, otherwise known as the mass moment of inertia, angular mass, second moment of mass, or most accurately, rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis, akin to how mass determines the force needed for a desired acceleration. It depends on the body's mass distribution and the axis chosen, with larger moments requiring more torque to change the body's rate of rotation. It is an extensive (additive) property: for a point mass the moment of inertia is simply the mass times the square of the perpendicular distance to the axis of rotation. The moment of inertia of a rigid composite system is the sum of the moments of inertia of its component subsystems (all taken about the same axis). Its simplest definition is the second moment of mass with respect to distance from an axis. For bodies constrained to rotate in a plane, only their moment of inertia about an ax ...

Conservation Of Angular Momentum
In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important physical quantity because it is a conserved quantity—the total angular momentum of a closed system remains constant. Angular momentum has both a direction and a magnitude, and both are conserved. Bicycles and motorcycles, frisbees, rifled bullets, and gyroscopes owe their useful properties to conservation of angular momentum. Conservation of angular momentum is also why hurricanes form spirals and neutron stars have high rotational rates. In general, conservation limits the possible motion of a system, but it does not uniquely determine it. The three-dimensional angular momentum for a point particle is classically represented as a pseudovector , the cross product of the particle's position vector (relative to some origin) and its momentum vector; the latter is in Newtonian mechanics. Unlike linear momentum, angular momentum d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
