+129852 Note that, the slope of the curve at any point is just the velocity at that point. So, from B to C, the slope approaches 0, indicating that the velocity (in the positive direction) is decreasing (but not yet = 0). And at C, the velocity = 0 (since the slope = 0 at that point). And from C to D, the velocity begins to increase again (in the negative direction) because the slope of the curve gets ever steeper between these two points. And note that, from D to E, the velocity slows again because the slope is aproaching 0.
+33661 Velocity is the slope of the curve of x against t. Between A and B the slope (hence the velocity) is increasing.
Between B and C the slope (hence the velocity) is decreasing (the velocity is still positive, but getting smaller).
