  2. Relative change - Wikipedia

    en.wikipedia.org/wiki/Relative_change

    The absolute change in this situation is 1 percentage point (4% − 3%), but the relative change in the interest rate is: % % % = … = %. In general, the term "percentage point(s)" indicates an absolute change or difference of percentages, while the percent sign or the word "percentage" refers to the relative change or difference.

  3. Linguistic frame of reference - Wikipedia

    en.wikipedia.org/wiki/Linguistic_frame_of_reference

    Linguistic frame of reference is a frame of reference as it is expressed in a language. A frame of reference is a coordinate system used to identify the physical location of an object. In languages, different frames of reference can be used. They are: the relative frame of reference, the intrinsic frame of reference, and the absolute frame of ...

  4. Relative and absolute tense - Wikipedia

    en.wikipedia.org/wiki/Relative_and_absolute_tense

    In the case of absolute tense, the grammatical expression of time reference is made relative to the present moment. It has been pointed out that the term is somewhat misleading, since this kind of time reference is not truly absolute, but is relative to the moment of speaking. [3] Most simple sentences in tensed languages exhibit absolute tense.

  5. Galilean invariance - Wikipedia

    en.wikipedia.org/wiki/Galilean_invariance

    An inertial frame is a reference frame in relative uniform motion to absolute space. All inertial frames share a universal time. Galilean relativity can be shown as follows. Consider two inertial frames S and S' . A physical event in S will have position coordinates r = (x, y, z) and time t in S, and r' = (x' , y' , z' ) and time t' in S' .

  6. Frame of reference - Wikipedia

    en.wikipedia.org/wiki/Frame_of_reference

    In physics and astronomy, a frame of reference (or reference frame) is an abstract coordinate system, whose origin, orientation, and scale have been specified in physical space. It is based on a set of reference points , defined as geometric points whose position is identified both mathematically (with numerical coordinate values) and ...

  7. Language and spatial cognition - Wikipedia

    en.wikipedia.org/wiki/Language_and_Spatial_Cognition

    Costs of computation: Based on the assumption of language promoting the formation of different categories, it would result that the cognitive effort to access the more salient frame of reference in the respective language (relative, absolute or intrinsic) is lower in comparison to switching to another frame. [2] [26]

  8. Absolute difference - Wikipedia

    en.wikipedia.org/wiki/Absolute_difference

    The absolute difference is used to define other quantities including the relative difference, the L 1 norm used in taxicab geometry, and graceful labelings in graph theory. When it is desirable to avoid the absolute value function – for example because it is expensive to compute, or because its derivative is not continuous – it can ...

  9. Motion - Wikipedia

    en.wikipedia.org/wiki/Motion

    In physics, motion is when an object changes its position with respect to a reference point in a given time. Motion is mathematically described in terms of displacement , distance , velocity , acceleration , speed , and frame of reference to an observer, measuring the change in position of the body relative to that frame with a change in time.
