Suppose that a bus is traveling at 50 mi/h cast along Main Street- and that you're on the bus running to the front of the bus at 10 mi/h. What is your velocity relative to Main Street? That's easy...60 mi/h east. Vectors are not necessary to solve this problem. However, if you can understand how vectors work in simple situations as shown below, then you can understand how they work in more complex situations. = 50 mi /h east v,-10 mi/h east Vector Representation R=+v = 60 mi /h east Arrows are used to depict each vector. R represents the resultant of adding the vectors in question. R is also a vector. Q2 How is the magnitude of each vector depicted graphically? Q3 How is the direction of each vector indicated?
