Numbered Heads Chap 3 Review

Numbered Heads Instructions

1. Form into the designated groups

2. Take out one full sheet of paper per group and list the name of the group at the top. Then list the names of the group members and place numbers next to each name (1, 2, 3…..If four members then write 4 also). It doesn’t matter who gets what number.

3. Hand the paper to the instructor. It will be used for assessment and graded.

4. Begin reviewing/ learning the listed concepts. Make up sample questions related to the concept. Try and figure out what question the teacher will ask. Time is limited; so don’t waste it!

5. Once you understand the concepts make sure each group members also understand by assessing them. Do not ask yes or no assessment questions.

Good Assessment. “Sam, could you show me how to do number three on the list?”

Poor Assessment. “Do you guys all know it?”

6. When the instructor calls a number randomly (ex. = 3) the three will go to a designated area alone and respond to a similar question. Make sure they have something to write with and a calculator. After they leave begin studying the next set of concepts for the next round.

7. After a short amount of time the person will then return to the group and their answer will be graded by the teacher and given to the entire group as a communal score.

8. The returning group member may be called again so they should receive extra instruction to help get caught up.

9. The scores are added at the end to determine winners. The top three groups receive extra points on the test.

Graph Matching

Computer 1

One of the most effective methods of describing motion is to plot graphs of position, velocity, and acceleration vs. time. From such a graphical representation, it is possible to determine in what direction an object is going, how fast it is moving, how far it traveled, and whether it is speeding up or slowing down. In this experiment, you will use a Motion Detector to determine this information by plotting a real time graph of your motion as you move across the classroom.

The Motion Detector measures the time it takes for a high frequency sound pulse to travel from the detector to an object and back. Using this round-trip time and the speed of sound, you can determine the position of the object. Logger Pro will perform this calculation for you. It can then use the change in position to calculate the object’s velocity and acceleration. All of this information can be displayed either as a table or a graph. A qualitative analysis of the graphs of your motion will help you develop an understanding of the concepts of kinematics.

PRELIMINARY QUESTIONS

1. Use a coordinate system with the origin at far left and positive positions increasing to the right. Sketch the position vs. time graph for each of the following situations:

• An object at rest • An object moving in the positive direction with a constant speed • An object moving in the negative direction with a constant speed • An object that is accelerating in the positive direction, starting from rest

2. Sketch the velocity vs. time graph for each of the situations described above.

PROCEDURE Part l Preliminary Experiments

1. Connect the Motion Detector to the DIG/SONIC 1 channel of the interface. If the Motion Detector has a sensitivity switch, set it to Normal.

2. Place the Motion Detector so that it points toward an open space at least 4 m long. Use short strips of masking tape on the floor to mark the 1 m, 2 m, 3 m, and 4 m positions from the Motion Detector.

3. Open the file “01a Graph Matching” from the Physics with Vernier folder.

4. Using Logger Pro, produce a graph of your motion when you walk away from the detector with constant velocity. To do this, stand about 1 m from the Motion Detector and have your lab partner click . Walk slowly away from the Motion Detector when you hear it begin to click.

5. Sketch what the position vs. time graph will look like if you walk faster. Check your prediction with the Motion Detector.

6. Try to match the shape of the position vs. time graphs that you sketched in the Preliminary Questions section by walking in front of the Motion Detector.

Part Il Position vs. Time Graph Matching 7. Open the experiment file “01b Graph Matching.” A position vs. time graph will appear. 8. Describe how you would walk to produce this target graph.

9. To test your prediction, choose a starting position and stand at that point. Start data collection by clicking . When you hear the Motion Detector begin to click, walk in such a way that the graph of your motion matches the target graph on the computer screen.

10. If you were not successful, repeat the process until your motion closely matches the graph on the screen. If a printer is attached, print the graph with your best attempt.

11. Open the experiment file “01c Graph Matching” and repeat Steps 8–10, using a new target graph.

12. Answer the Analysis questions for Part II before proceeding to Part III.

Part IIl Velocity vs. Time Graph Matching 13. Open the experiment file “01d Graph Matching.” A velocity vs. time graph will appear.

1 - 2 Physics with Vernier

14. Describe how you would walk to produce this target graph.

15. To test your prediction, choose a starting position and stand at that point. Start by clicking . When you hear the Motion Detector begin to click, walk in such a way that the graph

of your motion matches the target graph on the screen. It will be more difficult to match the velocity graph than it was for the position graph.

16. Open the experiment file “01e Graph Matching.” Repeat Steps 14–15 to match this graph. 17. Remove the masking tape strips from the floor.

ANALYSIS Part II Position vs. Time Graph Matching

1. Describe how you walked for each of the graphs that you matched.

2. Explain the significance of the slope of a position vs. time graph. Include a discussion of positive and negative slope.

3. What type of motion is occurring when the slope of a position vs. time graph is zero?

4. What type of motion is occurring when the slope of a position vs. time graph is constant?

5. What type of motion is occurring when the slope of a position vs. time graph is changing? Test your answer to this question using the Motion Detector.

6. Return to the procedure and complete Part III.

Part III Velocity vs. Time Graph Matching 7. Describe how you walked for each of the graphs that you matched.

8. What type of motion is occurring when the slope of a velocity vs. time graph is zero? 9. What type of motion is occurring when the slope of a velocity vs. time graph is not zero? Test

your answer using the Motion Detector.
