Example text

H. b e) ä-b=-1, also ä nicht f) ä. h. 0, J. b J. 1 Der mathematische Funktionsbegriff Vorbemerkung: Bei einem frei fallenden Stein wird die Fallgeschwindigkeit umso größer, je länger er gefallen ist . Die Fallgeschwindigkeit hängt von der Zeit ab. Geschwindigkeit und Zeit sind beobachtbare und meßbare Größen . Eindeutige Abhängigkeiten zwischen Beobachtungsgrößen gaben Anlaß, Naturgesetze zu formulieren. Das obige Problem hat bekanntlich Galilei untersucht. Seine Methode ist exemplarisch für das Auffinden physikali~cher Zusammenhänge geworden.

Bei Drehbewegungen gilt, daß die Bahngeschwindigkeit eines beliebigen Punktes das Vektorprodukt aus Winkelgeschwindigkeit und einem Ortsvektor von der Drehachse zum Punkt P ist. Die Drehachse in der Abbildung ist die z-Achse. Die Winkelgeschwindigkeit betrage w. Der Ortsvektor zum Punkt P habe die w Koordinaten = (0, ry, rz) . Die Winkelgeschwindigkeit w hat die Koordinaten (0, 0, wz). 1 Übungsaufgaben A Berechnen Sie das Skalarprodukt der Vektoren läl = läl = läl = läl = a) b) c) d) lbl = 2; lbl = 5; lbl = 4; lbl = 3; 3; 2; 1; 2,5; ä und b (ä,b) = i a = a = 0° a-!.

Dieselbe Richtung wie ä Der Vektor -Aä hat 1. die Länge Aa 2. die entgegengesetzte Richtung wie ä. Die Multiplikation eines Vektors mit einem Skalar ist besonders einfach, wenn die Komponenten des Vektors bekannt sind. Sei A eine reelle Zahl und sei ä = (a:r:, ay, az). Dann besitzt der Vektor Aä die Komponentendarstellung: Beispiel: Gegeben sei ä = (2, 5, 1) Dann haben die Vektoren 3ä und -3ä die Komponentendarstellungen: 3ä = (6, 15, 3) -3ä = (-6,-15,-3) Falls A = 0 ist, erhalten wir den Vektor (0, 0, 0) .
