Vectors: Magnitude, Direction, and Vector Addition

No. Date Physics. "Vectors" Those physical quantities which require Magnitude as Well as direction for their Complete representation and follows Vector laws. Vector chasified two types. Polar Vector these Vector have a starting part of application Such as diplacement Force. Axial Vector these vector Represent tationnal effect and act along the Axis of relations in accordance with Hgth hand Screw Rule . Properties of Vectors addition. Vector addition IS Commutative, I.e A+B BtA . Vector addition is associative. At (B+C) = B stCC+A). CHCAIB). Vector addition distributive m (A+B) = MAIMB. Ato. . A .

No. Date Addition OF Vectors TRiangle law of Vector. R I B Sino 601 A. IF two Vechor A and B acting ata point are inclined an angel O Resultant R= 1 A2 B2 + 2AB Cos O IF the Resultant Vector R. Subtend an angle B with Vector A then . tan B= Bsin 0 At B Coso 0. Parallelogram law of Vectors addition . B R. o B sinG B 0 A.
