  2. V2 word order - Wikipedia

    en.wikipedia.org/wiki/V2_word_order

    In syntax, verb-second (V2) word order [1] is a sentence structure in which the finite verb of a sentence or a clause is placed in the clause's second position, so that the verb is preceded by a single word or group of words (a single constituent). Examples of V2 in English include (brackets indicating a single constituent):

  3. Penthouse principle - Wikipedia

    en.wikipedia.org/wiki/Penthouse_principle

    The penthouse principle: The rules are different if you live in the penthouse. The penthouse named in the principle is the top floor of a high-rise apartment building, and is a metaphor for the matrix clause in a multi-clause structure (which, when diagrammed in usual phrase marker notation, contains the highest clause node in the structure).

  4. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    Example 3.5 and p.116 Bernoulli's principle can also be derived directly from Isaac Newton's second Law of Motion. When fluid is flowing horizontally from a region of high pressure to a region of low pressure, there is more pressure behind than in front. This gives a net force on the volume, accelerating it along the streamline. [a] [b] [c]

  5. Dynamic pressure - Wikipedia

    en.wikipedia.org/wiki/Dynamic_pressure

    The dynamic pressure, along with the static pressure and the pressure due to elevation, is used in Bernoulli's principle as an energy balance on a closed system. The three terms are used to define the state of a closed system of an incompressible , constant-density fluid.

  6. Snell's law - Wikipedia

    en.wikipedia.org/wiki/Snell's_law

    Given n lines L and a point P(L) on each line, find the locus of points Q such that the lengths of the line segments QP(L) satisfy certain conditions. For example, when n = 4, given the lines a, b, c, and d and a point A on a, B on b, and so on, find the locus of points Q such that the product QA*QB equals the product QC*QD.

  7. Verb–subject–object word order - Wikipedia

    en.wikipedia.org/wiki/Verb–subject–object...

    In languages with V2 word order, such as most Germanic languages except for Modern English, as well as Ingush and Oʼodham, the verb is always the second element in a main clause. The subject precedes the verb by default, but if another word or phrase is put at the front of the clause, the subject is moved to the position immediately after the ...

  8. Object–subject word order - Wikipedia

    en.wikipedia.org/wiki/Object–subject_word_order

    The Relevance Principle: The reference of the subject (phrase) determines in part, the relevance of what is said, regardless of what it is, to the addressee. In a typical sentence, the subject is the same as the topic , i.e. the thing that is being talked about.

  9. Subject–auxiliary inversion - Wikipedia

    en.wikipedia.org/wiki/Subject–auxiliary_inversion

    For exceptions to the principle that the inverted verb must be an auxiliary, see § Inversion with other types of verb below. It is also possible for the subject to invert with a negative contraction (can't, isn't, etc.). For example: a. He isn't nice. b. Isn't he nice? – The subject he inverts with the negated auxiliary contraction isn't
