Question 4: How do you move so the graph goes up steeply at first , and then continues up less steeply?
Question 5: How do you move to create a U-shaped graph?
Answer the following about two objects, A and B, whose motions produced the following position–time graphs.
Question 6A: Which object is moving faster?
Question 6B: Which starts ahead? Define what you mean by “ahead.”
Question 6C: What does the intersection mean?
Answer the following about two objects, A and B, whose motions produced the following position–time graphs.
Question 7A: Which object is moving faster?
Question 7B: Which object has a negative velocity according to the convention we have established?
Answer the following about two objects, A and B, whose motions produced the following position–time graphs.
Question 8A: Which object is moving faster?
Question 8B: Which starts ahead? Define what you mean by “ahead.”
For questions 9-13, select the position–time graph A to J (J being none of the graphs) corresponding to each description of the motion of an object below. Note that the positive x direction is toward the right, and the object moves along the positive portion of the x-axis.
Question 9: The object moves with a steady (constant) velocity to the right.
Question 10: The object is standing still at the origin
Question 11: The object moves with a steady (constant) velocity to the right for several seconds and then stands still for the same number of seconds.
For questions 12 and 13, select the position–time graph A to J (J being none of the graphs) corresponding to each description of the motion of an object below. Note that the positive x direction is toward the right, and the object moves along the positive portion of the x-axis.
Question 12: The object moves with a steady velocity to the right for several seconds, then reverses direction and moves at the same speed to the left for the same number of seconds.
Question 13: The object moves to the right, starting slowly and speeding up.
Questions 14-17. After studying the velocity–time graphs you have made, answer the following questions. Use phrases such as “speeding up”, “slowing down” or “constant velocity,” and “away” or “towards” to describe your motion.
Question 14: How would you move the IOLab to create graph A?
Question 15: How would you move the IOLab to create graph B?
Question 16: How would you move the IOLab to create graph C?
Question 17: How would you move the IOLab to create graph D?
Question 18: The velocity–time graph of an object is shown above. Figure out the total change in position (displacement) of the object.
The velocity graph below shows the motion of two objects, A and B. Answer the following questions. Explain your answers when necessary.
Question 19A: Is one object faster than the other? If so, which one is faster—A or B?
Question 19B: What does the intersection mean?
Question 19C: Can you tell which object is “ahead”? (Define “ahead.”)
Question 19D: Does either A or B reverse direction? Explain.
The velocity graph below shows the motion of two objects, A and B. Answer the following questions. Explain your answers when necessary.
Question 20A: Is one object faster than the other? If so, which one is faster—A or B? Explain your answer.
Question 20B: What does the intersection mean?
Question 20C: Can you tell which object is “ahead”? (Define “ahead.”)
Question 20D: Does either A or B reverse direction? Explain.
For questions 21-24, select the velocity–time graph A to
I corresponding to each description below of an object. Note that the positive x direction is toward the right, and the object moves along the positive portion of the x-axis.
Question 21: The object is moving to the right at a steady (constant) velocity.
Question 22: The object is standing still.
Question 23: The object moves to the left at a steady (constant) velocity for several seconds, and then stands still for the same number of seconds.
Question 24: The object moves to the right at a steady (constant) velocity for several seconds, reverses direction, and moves back to the left at the same speed for the same number of seconds.
Questions 25-27 Describe in words the velocity-time graph for an object whose motion produced each of the position–time graphs shown below. (Note: Unlike most real objects, you can assume that these objects can change velocity so quickly that it looks instantaneous with this time scale.)
Question 25:
Question 26:
Question 27:
