A flip trick is a type of skateboarding trick in which the skateboard rotates around its vertical axis, or its vertical axis and its horizontal axis simultaneously.
 The first flip trick called a kickflip, originally called a "magic flip," was invented by professional skateboarder Rodney Mullen.
The barberpole illusion is a visual illusion that reveals biases in the processing of visual motion in the human brain.
 This visual illusion occurs when a diagonally striped pole is rotated around its vertical axis (horizontally), it appears as though the stripes are moving in the direction of its vertical axis (downwards in the case of the animation to the right) rather than around it.
The 360 Crescent is a martial arts kick that received its name from the motion of the kick itself.
 It is also sometimes called, "360 kick", or "Jump spin kick".
 The practitioner jumps into the air and executes a 360 degree turn while keeping his or her body perpendicular to the ground.
 As soon as the kicker leaves the ground the kicking leg should be extended as straight and high as possible.
 The kicking leg is normally the same side as the direction that the practitioner is spinning.
 For example, it will be the right leg if the practitioner is spinning to the right or the left leg if the practitioner is spinning to the left.
A Jones diagram is a type of Cartesian graph developed by Loyd A. Jones in the 1940s, where each axis represents a different variable.
 In a Jones diagram opposite directions of an axis represent different quantities, unlike in a Cartesian graph where they represent positive or negative signs of the same quantity.
 The Jones diagram therefore represents four variables.
 Each quadrant shares the vertical axis with its horizontal neighbor, and the horizontal axis with the vertical neighbor.
 For example, the top left quadrant shares its vertical axis with the top right quadrant, and the horizontal axis with the bottom left quadrant.
 The overall system response is in quadrant I; the variables that contribute to it are in quadrants II through IV.
Camber angle is the angle made by the wheels of a vehicle; specifically, it is the angle between the vertical axis of the wheels used for steering and the vertical axis of the vehicle when viewed from the front or rear.
 It is used in the design of steering and suspension.
 If the top of the wheel is farther out than the bottom (that is, away from the axle), it is called positive camber; if the bottom of the wheel is farther out than the top, it is called negative camber.
In dance and gymnastics, a turn is a rotation of the body about the vertical axis.
 It is usually a complete rotation of the body, although quarter (90°) and half (180°) turns are possible for some types of turns.
 Multiple, consecutive turns are typically named according to the number of 360° rotations (e.g., "double" or "triple" turn).
A turn board (also known as turning board) is a training device commonly used in the fields of Ballet, dance, ice skating, and other athletics in order to aid in the development of various dance turns.
 It is believed that regular use of a turning board may increase confidence and comfort while performing various moves that involve turns.
 In dance and gymnastics, a turn is a rotation of the body about the vertical axis.
 It is usually a complete rotation of the body, although quarter (90°) and half (180°) turns are possible for some types of turns The TurnBoard was developed by Ballet Is Fun, and it has become the world's most popular ballet training product.
 Most recently, a new turn training tool, the Turning Pointe, has been released by Je Ballet with a dedicated relevé platform.
In terms of knowledge representation, a living graph (also referred to as a "lifeline", "living timeline" or "fortune line".)
 is a graph similar to a chronology timeline which places events along a vertical axis to reflect changes over time.
 The vertical axis can be used to represent many factors, such as relative importance, degrees of success/failure, danger/safety or happiness/sadness.
 In this sense they have been described as being "timelines with attitude".
An altazimuth or alt-azimuth mount is a simple two-axis mount for supporting and rotating an instrument about two perpendicular axes – one vertical and the other horizontal.
 Rotation about the vertical axis varies the azimuth (compass bearing) of the pointing direction of the instrument.
 Rotation about the horizontal axis varies the altitude (angle of elevation) of the pointing direction.
In two-sector macroeconomic models, a Harrod–Johnson diagram is a way of visualizing the relationship between the output price ratios, the input price ratios, and the endowment ratio of the two goods.
 Often the goods are a consumption and investment good, and this diagram shows what will happen to the price ratio if the endowment changes.
 The diagram juxtaposes a graph which has input price ratios as its horizontal axis, endowment ratios as its positive vertical axis, and output price ratios as its negative vertical axis.
 This may seem unintuitive, but doing this makes it easier to see the relationship between the output price ratios and the endowment.
 The diagram is named after economists Roy F. Harrod and Harry G. Johnson.

Question: What is a rotation of the body about the vertical axis that is known to be executed while completing a 360 Crescent kick?
Answer: In dance and gymnastics, a turn is a rotation of the body about the vertical axis.
