Body relative directions (also known as egocentric coordinates) are geometrical orientations relative to a body such as a human person's body or a road...

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...

and W respectively. Relative to north, the directions east, south, and west are at 90 degree intervals in the clockwise direction. The ordinal directions...

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...

and a body, when there is relative motion, can only be transmitted by normal pressure and tangential friction stresses. So, for the whole body, the drag...

aeronautics, the relative wind is the direction of movement of the atmosphere relative to an aircraft or an airfoil. It is opposite to the direction of movement...

continuous set of displacements, called the motion of M relative to F. The motion of a body consists of a continuous set of rotations and translations...

degrees. Thus, it is the same as azimuth. Relative bearing refers to the angle between the craft's forward direction (heading) and the location of another...

explained below. The escape velocity relative to the surface of a rotating body depends on direction in which the escaping body travels. For example, as the Earth's...

Upright may refer to: Body relative direction, the geometrical orientation of a person etc. Upright (TV series), Australian drama Upright Technologies...

nonliving objects, to have an orientation, described by the concept of body relative direction. Aristotle reasoned that concepts of "front" and "back" were only...

mechanics that describes the motion of bodies. Velocity is a physical vector quantity: both magnitude and direction are needed to define it. The scalar absolute...

scientific fields, are the two types of chirality ("handedness") or relative direction. The terms are derived from the Latin words for "left" (sinister)...

energy as any other body at the same temperature. It is a diffuse emitter: measured per unit area perpendicular to the direction, the energy is radiated...

change of its angular position relative to the origin. [citation needed] Spin angular velocity refers to how fast a rigid body rotates with respect to its...

any direction. Spondylolisthesis is graded based upon the degree of slippage of one vertebral body relative to the subsequent adjacent vertebral body. Spondylolisthesis...

the property that the body is rigid, namely that all its particles maintain the same distance relative to each other. If the body is rigid, it is sufficient...

force exerted on a body by the air (or other gas) in which the body is immersed, and is due to the relative motion between the body and the gas. There...

when a body is constrained to move only along a straight line. Its position can then be given by a single number, indicating where it is relative to some...

relates more to IBW than total body weight. The term was based on the use of insurance data that demonstrated the relative mortality for males and females...

may also be described as a relative position (resulting from the motion), that is, as the final position xf of a point relative to its initial position xi...

body has its own distinct center of rotation, then the relative center of rotation between the bodies has to lie somewhere on the line connecting the two...

a direction perpendicular to two quantities: the angular velocity of the rotating frame relative to the inertial frame and the velocity of the body relative...

body relative to a larger orbiting body. The osculating (instantaneous) orbital period of the smaller body remains very near that of the larger body,...

acceleration of a body relative to a free-fall condition, is measured by an instrument called an accelerometer. In classical mechanics, for a body with constant...

frequency, the intensity of radiation which is emitted and reflected from a body relative to other frequencies (that is, the net amount of radiation leaving its...

In mechanics, strain is defined as relative deformation, compared to a reference position configuration. Different equivalent choices may be made for the...

that at this time body snatching was frequent". Body snatching became so prevalent in the UK that it was not unusual for relatives and friends of someone...

Clockwise motion (abbreviated CW) proceeds in the same direction as a clock's hands relative to the observer: from the top to the right, then down and...

driven wheels placed on either side of the robot body. It can thus change its direction by varying the relative rate of rotation of its wheels and hence does...
