When the condition refers to the past, but the consequence to the present, the condition clause is in the past perfect (as with the third conditional), while the main clause is in the conditional mood as in the second conditional (i.e. simple conditional or conditional progressive, but not conditional perfect).
Equation [3] involves the average velocity v + v 0 / 2 . Intuitively, the velocity increases linearly, so the average velocity multiplied by time is the distance traveled while increasing the velocity from v 0 to v, as can be illustrated graphically by plotting velocity against time as a straight line graph. Algebraically, it follows ...
In terms of a displacement-time (x vs. t) graph, the instantaneous velocity (or, simply, velocity) can be thought of as the slope of the tangent line to the curve at any point, and the average velocity as the slope of the secant line between two points with t coordinates equal to the boundaries of the time period for the average velocity.
A conditional statement may refer to: A conditional formula in logic and mathematics, which can be interpreted as: Material conditional; Strict conditional;
A conditional sentence expressing an implication (also called a factual conditional sentence) essentially states that if one fact holds, then so does another. (If the sentence is not a declarative sentence, then the consequence may be expressed as an order or a question rather than a statement.)
The optative mood (/ ˈ ɒ p t ə t ɪ v / OP-tə-tiv or / ɒ p ˈ t eɪ t ɪ v / op-TAY-tiv; [1] abbreviated OPT) is a grammatical mood that indicates a wish or hope regarding a given action.It is a superset of the cohortative mood and is closely related to the subjunctive mood but is distinct from the desiderative mood.
(2) If the fair coin had been flipped, it would have landed tails (i.e. not heads). On Stalnaker's analysis, there is a closest world where the fair coin mentioned in (1) and (2) is flipped and at that world either it lands heads or it lands tails. So either (1) is true and (2) is false or (1) is false and (2) true.
Examples are the English and French conditionals (an analytic construction in English, [c] but inflected verb forms in French), which are morphologically futures-in-the-past, [1] and of which each has thus been referred to as a "so-called conditional" [1] [2] (French: soi-disant conditionnel [3] [4] [5]) in modern and contemporary linguistics ...
