Chapter 3 Vectors Vectors are quantities which contain both magnitude and direction. Example velocity. Velocity = Vector Quantity is specified by three numbers that give its magnitude and direction (or its components in three perpendicular directions). Two vectors are equal if they have the same magnitude and direction even if they are parallel. Displacement is the direct distance (straight line) from the initial position to the final position. Subtracting vectors Net displacement is the distance from initial position To final position without any of the intermediate displacements. Combining

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 x-component A x is the magnitude of the component vector . 2. The sign of A x is positive if points in the positive x-direction, negative if points in the negative x-direction. 3. The y- and z-components, A y and A z , are determined similarly. 4. The “x-component” 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.
