... direction of motion does an amount of work given by W Fd. A force exerted perpendicular to the motion does no work. What work does a force exerted at an angle do? For example, what work does the person pushing the lawn mower in Figure 10–4a do? You know that any force can be replaced by its compon ...

... That is, its initial point is at the origin and its terminal point is at (3, 5). You can think of this vector as the resultant of a horizontal vector with a magnitude of 3 units and a vertical vector with magnitude of 5 units. Since vectors with the same magnitude and direction are equal, many vecto ...
