If you leave home and walk a distance of 10 km, you might end up your walk 10km east of home, 5km east of home or back at your home. Your final position or displacement depends not only on the distance you travel but also the direction in which you walk. Displacement includes both the distance and the direction of change in position, measured from the starting point. Therefore, displacement is a vector quantity and can be drawn to scale represented by an arrow-tipped line segment. The length of the arrow drawn to scale represents the magnitude of the quantity. The direction of the arrow represents the direction of the quantity. The vectors are added by placing the tail of one vector at the head of the other vector. The sum or resultant is drawn by connection of the tail of the first vector to the head of the second vector. Materials: Sharp pencilPaperRulerProtractor  Procedure and Questions: Show all work Use the scale on the map and determine the distance in meters From Grandville Road along N 11th Street to Church Street and down Church Street to the YMCA. Along Moull Street from N 21st Street to Mt. Vernon Road. Take a walk from the corner of N 21st Street and Granville Road down N 21st Street to Church Street and down Church to the YMCA. Using the map scale, find the magnitude in meters of each of the distances. Using a scale of 1cm = 92m, draw a vector diagram representing your trip. Measure the resultant displacement on your diagram and express it in meters. Calculate the resultant algebraically. Return to the map and measure the total displacement using the map scale. How do your result compare? What distance did you walk? Using the scale of 1cm=92m, draw a vector diagram for the following trip. Start at Newark High School and go down Breman to Granville Road, then along Granville Road to N 11th Street and down N 11th Street to Whites Field. From your diagram, determine in meters the distance traveled. Determine the total displacement using your diagram. Determine the total displacement from you original map. Explain why there might be a difference between your answers to b and c. 1cm = 210m W S E N N 11th St Whites Field YWCA YMCA Newark HS West Main Street 6th St. Church Street N 21st Street Granville Road Breman King Ave Mt.
