Constants Which of the graphs shown is the correct v vs. t plot for the motion described in the previous parts? To describe the motion of a particle along a straight line, it is often convenient to draw a graph representing the position of the particle at different times. This type A B of graph is usually referred to as an I vs. t graph. To U (m/s) U (m/s) draw such a graph, choose an axis system in which time t is plotted on the horizontal axis and position T 0.8 0.8 0.6 0.6 Figure
