Much like velocity, you can make a graph of acceleration vs. time by plotting the rate of change of an object’s velocity (its acceleration) on the y-axis, and placing time on the x-axis. As shown here in this graph, this graph shows the velocity as a function all the time. And in this graph, the y-intercept is v 0. Since the velocity versus time graph in Figure 3 (b) is a straight line, its slope is the same everywhere, implying that acceleration is constant. The region “cd” represents decreasing acceleration indicating that slope decreases with the time axis which also corresponds to decreasing acceleration and “de” represents constant velocity with zero acceleration. 1) At first, the acceleration opposes the direction of velocity and the object must be slowing down. In Figure \(\PageIndex{1}\), we see that if we extend the solution beyond the point when the velocity is zero, the velocity becomes negative and the boat reverses direction.
