WebThis is the formula for the addition of vectors: Given two vectors a = (a 1, a 2) and b = (b 1, b 2 ), then the vector sum is, M = (a 1 + b 1, a 2 + b 2) = (M x, M y ). In this case, magnitude of the resultant vector sum M = M = √ ( (M x) 2 + (M y) 2) and the angle can be computed as θ = tan -1 (M y / M x) What is the Vector Addition Rule? WebA vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity.
