Different from instantaneous speed, average speed is defined as the total distance covered divided by the time interval. For example, if a distance of 80 kilometres is driven in 1 hour, the average speed is 80 kilometres per hour. Likewise, if 320 kilometres are travelled in 4 hours, the average speed is also 80 kilometres per hour.
Synthetic phonics refers to a family of programmes which aim to teach reading and writing through the following methods: [2] Teaching students the correspondence between written letters and speech sounds (), known as “grapheme/phoneme correspondences” or “GPCs” or simply “letter-sounds”.
In linguistics, a grapheme is the smallest functional unit of a writing system. [1] The word grapheme is derived from Ancient Greek gráphō ('write'), and the suffix -eme by analogy with phoneme and other emic units. The study of graphemes is called graphemics. The concept of graphemes is abstract and similar to the notion in computing of a ...
The difference between average and median speeds is the way individual measurements are aggregated. Average speeds are more commonly used but can give a wrong impression of the actual user experience since fast connections can bias the average results.
Graphemics or graphematics is the linguistic study of writing systems and their basic components, i.e. graphemes.. At the beginning of the development of this area of linguistics, Ignace Gelb coined the term grammatology for this discipline; [1] later some scholars suggested calling it graphology [2] to match phonology, but that name is traditionally used for a pseudo-science.
For example, the grapheme à requires two glyphs: the basic a and the grave accent `. In general, a diacritic is regarded as a glyph, [2] even if it is contiguous with the rest of the character like a cedilla in French, Catalan or Portuguese, the ogonek in several languages, or the stroke on a Polish "Ł". Although these marks originally had no ...
The scalar absolute value of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s −1). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector.
The Solomon curve is a graphical representation of the collision rate of automobiles as a function of their speed compared to the average vehicle speed on the same road. The curve was based on research conducted by David Solomon in the late 1950s and published in 1964. [ 1 ]
