1.2 Displacement vs Distance (STUDENT EXERCISE) ONE DIMENSIONAL VECTORS ( The X-Axis) Greenbush Line West Hingham North Scituate East yarmouth Nantasket South Station Weymouth Cohasset Braintree Greenbush Landing 3 2 -1 0 1 2 3 4 5 6 7 0 9 10 11 12 13 14 15 For the purposes of this exercise we are assuming the Greenbush line is a straight line like a number line. Scale is in miles. For straight line motion: Displacement = AX = (Xfinal - Xinitial ) * * * * REMEMBER TO INCLUDE UNITS ON ALL NUMBERS FOR FULL CREDIT *** * 1. What is the displacement vector that will bring you from Cohasset all the way in to South Station? (Draw it and state the magnitude and direction (to the right is +, to the left is -) ) 2. How does the magnitude of the displacement vector compare to the distance (length of path from start to finish)
