The figure below shows the typical trajectory a basketball player might travel as he makes a jump. You can visually see that almost half the hang time is spent near the top of the arc. Using some mathematics one can calculate the time spent in the top part of the jump.
A red octagon symbolizes stop even without the word. A symbol is an object or a concept that represents, stands for or suggests another idea, visual image, belief, action or material entity. Symbols take the form of words, sounds, gestures, ideas or visual images and are used to convey other ideas and beliefs. For example, a red octagon may be a symbol for STOP.
Definition: A person, place, action, word, or thing that (by association, resemblance, or convention) represents something other than itself. Verb: symbolize. Adjective: symbolic.In the broadest sense of the term, all words are symbols.(See also sign .) In a literary sense, says William Harmon, a symbol combines a literal and sensuous quality with an abstract or suggestive aspect (A Handbook to Literature, 2006). In language studies, symbol is sometimes used as another term for logograph. In Poe's 'The Raven,' death isn't the symbol; the bird is. 2  In Crane's The Red Badge of Courage, courage isn't the symbol; blood is. 3  Symbols are usually objects, but actions can also work as symbols--thus the term 'symbolic gesture.'.  4 A symbol means more than itself, but first it means itself.
