  1. DRAWING SCALED VECTOR DIAGRAMS

  2. Read the problem carefully. • Determine what values are being represented. • Determine an appropriate scale and record it on the diagram. • Draw the first vector using the scale and label it. • Place the next vector at the tip of the first at the proper angle. • Connect the tail of the first vector to the tip of the second. • Use the scale to determine the value and record it on the diagram.

  3. Ex. A bear traveled 500m due east then turned and traveled 800m due north. Find the bears displacement. Scale: 1cm= 100m 9.5cm = 950m 8.0cm = 800m 58˚ 5.0cm =500m C =950m@58˚NE

  4. Ex2. A car travels 3.5km due north then 6.0km due east. It then travels due south 1km. What is the cars displacement ? scale: 1cm = 1km 6cm = 6km 1.0km 3.5cm= 3.5km 68˚ 6.7cm=6.7km C = 6.7km@68˚NE
