Vectors and Vector Addition A vector is a physical quantity that has both magnitude and direction . The displacement of an object from position A to position B is a vector A B If the distance measured from A to B is 2.0 m, the magnitude of the vector is 2 m The direction of a vector is given by specifying the angle the vector makes with the positive x-axis x θ The displacement vector has a magnitude 2 m and its direction is specified by the angle θ . 2.0 m The displacement vector makes an θ with the positive x-axis A vector is represented by drawing an arrow, its length represents the magnitude and the arrow represents the direction. 1

Vector Components The displacement from A to B can be achieved by first moving from A to C and then from C to B A B Vector AC is along the x-axis. Vector CB is along the y-axis. x θ 2.0 m Vector AB is obtained by adding vector AC to vector CB C AB AC CB = + It is called the y-component of vector AB It is called the x-component of vector AB 2

A B x θ If v is a vector that makes an angle θ with the x-axis, v x = v cos θ In the right triangle ABC, side AC is the adjacent side and BC is the opposite side for angle θ . AB is the hypotenuse.
