The position-time graph describes the motion of a moving object. Describe the motion represented by each segment of the graph. A graph with time (s) on the x-axis and position (m) on the y-axis. Point A is at (20, 0), point B is at (20, 20), point C is at (40, 40), point D is at (60, 60), point E is at (80, 60), and point F is at (100, 80). A horizontal line connects points A and B, and another horizontal line connects points D and E. A diagonal line connects points C and D. A curve connects points B and C, rising slowly near B and more quickly near C. Another curve connects points E and F, rising quickly near E and slowly near F.
