Unformatted text preview: A . Where B will have the same direction but 3 times the magnitude of A. Vector –A is has equal magnitude but opposite direction of A. . thus A+(A) = 0 Determining the Components of a Vector 1. The absolute value  A x  of the xcomponent A x is the magnitude of the component vector . 2. The sign of A x is positive if points in the positive xdirection, negative if points in the negative xdirection. 3. The y and zcomponents, A y and A z , are determined similarly. 4. The “xcomponent” A x is a scalar . 5. The “component vector” is a vector that always points along the x axis. 6. The “vector” is , and it can point in any direction. Unit Vectors x A r x A r x A r...
