2J Slope and Motion Graphs Skill and Practice Page 2 of 3 Practice: Graph 1 Answer the questions about each graph. Position vs. Time 20 1. Graph 1 shows that the object (choose one): a. remains at rest. Position (km) b. moves away from the origin at a constant rate. C. moves toward the origin at a constant rate. d. accelerates. Time (h ) 2. What is the object's velocity? Show your work, and don't forget to give the correct velocity unit. 3 . What is the object's acceleration? Explain. Graph 2 4. Graph 2 shows that the object (choose one): Postion vs. Time a. remains at rest. 80 b. moves away from the origin at a constant rate. Position ( moves toward the origin at a constant rate. 40 20 slows down. 5. What is the object's velocity? Show your work. Time (S ) O Graph 3 6. Graph 3 shows that the object (choose one): Velocity vs. Time a . remains at rest. 15 b. speeds up as it moves away from the origin. C . 10 speeds up as it moves toward the origin. d. moves away from the origin at a constant rate. Velocity (m/s) 7. What is the object's acceleration? Show your work. -10 -15 -20 2 3 Time (s)
