Three line segments with the same direction. In geometry, direction, also known as spatial direction or vector direction, is the common characteristic of all rays which coincide when translated to share a common endpoint; equivalently, it is the common characteristic of vectors (such as the relative position between a pair of points) which can be made equal by scaling (by some positive scalar ...
Changing orientation of a rigid body is the same as rotating the axes of a reference frame attached to it.. In geometry, the orientation, attitude, bearing, direction, or angular position of an object – such as a line, plane or rigid body – is part of the description of how it is placed in the space it occupies. [1]
Circumferential (or azimuthal) – following around a curve or circumference of an object. For instance: the pattern of cells in Taylor–Couette flow varies along the azimuth of the experiment. Tangential – intersecting a curve at a point and parallel to the curve at that point. Collinear – in the same line; Parallel – in the same direction.
The terms are mainly used in discussing images of humans, whether in art history, medical contexts such as x-ray images, or elsewhere, but they can be used in describing any object that has an unambiguous front and back (for example furniture [2]) or, [3] when describing things that move or change position, with reference to the original position.
Forward is defined as the direction in which the object is moving. Backward is then defined as the opposite direction to forward. Alternatively, 'forward' may be the direction pointed by the observer's nose, defining 'backward' as the direction from the nose to the sagittal border in the observer's skull. With respect to a ship 'forward' would ...
In classical physics, translational motion is movement that changes the position of an object, as opposed to rotation.For example, according to Whittaker: [1] If a body is moved from one position to another, and if the lines joining the initial and final points of each of the points of the body are a set of parallel straight lines of length ℓ, so that the orientation of the body in space is ...
Joint attention, shared focus of two people on an object, resulting from pointing or other cues; List of gestures used in non-verbal communication; Ostensive definition, conveys the meaning of a term by pointing out examples; Pointing breed, dogs trained to find and indicate the direction of game
The XII position is true north. A clock position, or clock bearing, is the direction of an object observed from a vehicle, typically a vessel or an aircraft, relative to the orientation of the vehicle to the observer. The vehicle must be considered to have a front, a back, a left side and a right side.
