From Law of vector addition pdf ,vector addition is commutative in nature i.e. For example, when power is multiplied by time t, we get the quatity, work done. Polygon Law of Vector Addition states that if there are multiple coplanar (same plane) vectors acting on a same point simultaneously such that they each one, when put in one order, represents a side of a regular (open) polygon both in magnitude and direction then the resultant of all these vectors will be the closing side of that regular polygon taken in reverse order. Addition of Vectors and its Characteristics; Triangle Law of Vector Addition; Parallelogram Law of Vector Addition; Polygon Law of Vector Addition; Subtraction of Vectors; Multiplication of Vector by Scalar; Scalar and Vector Product of Vectors. Polygon Law of Vector Addition - definition Polygon law of vector addition states that if a number of vectors can be represented in magnitude and direction by the sides of a polygon taken in the same order, then their resultant is represented in magnitude and direction by the closing side of the polygon taken in the opposite order. Polygon Law of Vectors Addition: It states that, if number of vectors acting on a particle at a time are represented in magnitude and direction by the various sides of an open polygon taken in same order, then their resultant vector is represented in magnitude and direction by the closing side of polygon taken in opposite order. State the Polygon law of vector addition. Parallelogram Law of Vector Addition If two vectors acting simultaneously at a point are represented both in magnitude and direction by two adjacent sides of parallelogram drawn from the point, then the diagonal of parallelogram through that point represents the resultant both in magnitude and direction. is angle between them . For example, if a chain … “A vector is a directed at an angle to the horizontal (or the vertical) can be thought of as having two parts (or components). the following law of vector addition. What do you means by Multiplication of vector by a real number ? Draw the first vector using a scale.2. This is known as the parallelogram law of vector addition.
