Homework Help: Real simple vt graphs

  1. Jan 27, 2005 #1
    hey everyone,
    so i kno that the area underneath the lines represent displacement and that the slope of the lines on vt graphs represent acceleration but how do i go about measurign them and actually getting numbers answers? See the question i am trying to answer shows a vt graph and asks me to construct a a and d graph corresponding with it....help would be much appreciated thank you

    well if the graph is just consists of straight lines then divide it in to triangles and trapeziums and calculate the area.
    as for finding the slope of the lines use this (y2 - y1) / (x2 - x1). it is the "rise" over "run".
