HOMEWORK Description

PHYS 204 Week 2 iLab 3

  1. Paste your graphs from Step 1 (Constant Velocity Away) of the procedure here.
  2. What is the average velocity that you found in Step 1?
  3. What is the average acceleration that you found in Step 1?
  4. Paste your graphs from Step 2 (Constant Velocity Towards) of the procedure here.
  5. What is the major difference between the velocity data in Steps 1 and 2?
  6. Paste your graphs from Step 3 (Acceleration Away) of the procedure here.
  7. What were the average accelerations that you found from the straight-line fits to the velocities?
  8. What feature of your velocity graphs signifies that the motion of the cart is away from the sensor?
  9. What feature of your velocity graphs signifies that the cart is speeding up?
  10. Paste your graphs from Step 4 (Acceleration Toward and Away) of the procedure here.
  11. Is there a significant change in the velocity-time graph at the instant of closest approach?
  12. Make a straight-line fit of the velocity-time graph.
  13. How does the average acceleration (slope) compare to the acceleration found in the previous item?
  14. Paste your graphs from Step 5 (Acceleration Towards) of the procedure here.
  15. Fill in the table below. Use the results of all your measurements. Do not fill the chart with numbers. Use a plus sign if the quantity is positive and a minus sign if it is negative.

PHYS 204 Week 2 iLab 2

  1. Paste the first position-time graph below.
  2. Describe the difference between a position-time graph made by walkingslowly away from the sensor and one made by walking away quickly.
  3. Describe the difference between a position-time graph made by walking slowlyaway from the sensor and one made by walking toward the sensor slowly.
  4. Paste the position-time graph with your prediction for Item 16 below.
  5. Is your prediction the same as the final result? If not, describe how you would move to make a graph that looks like your prediction.
  6. Paste the first velocity-time graph below.
  7. What is the most important difference between a velocity-time graph made by slowly walking away and one made by quickly walking away?
  8. How are the velocity-time graphs different for motion away and motion toward the sensor?
  9. Paste the velocity-time graph with your prediction for Item 18 below.
  10. Is your prediction the same as the final result? If not, describe how you would move to make a graph that looks like your prediction.
  11. Place the graphs from Item 19 below.
  12. What is the average velocity that you calculated from the velocity-time graph?
  13. Record the equation of the fit that you found from the position-time graph. Compare the slope with the average velocity recorded above.
  14. What is the meaning of the y-intercept from the fit?
  15. How can you tell from a velocity-time graph that the moving object has changed direction? What is the velocity at the moment the direction changes?

HOMEWORK Description

PHYS 204 Week 1 iLab 1

  1. (1 point) What is the precision of the caliper?
  2. (2 points) Record your measurements of the diameter of the quarter in the table below.
  3. (2 points) Record your measurements of the thickness of the quarter in the table below.
  4. (0 points) Which coin did you choose for the next part of the experiment?
  5. (2 points) Record your measurements of the diameter of the coin in the table below.
  6. (2 points) Record your measurements of the thickness of the coin in the table below.
  7. (1 point) Why is it a good idea to average your measurements?
  8. (1 point) What is the precision of your diameter measurements?
  9. (1 point) What is the precision of your thickness measurements?
  10. (3 points) Use the averages of your measurements and the coin masses listed in the table in the introduction, and calculate the volume and density for the quarter and your coin. Record your results in the table below. Be sure to use the appropriate number of significant digits and correct units.
  11. (1 point) Is the coin you chose made of the same metal as the quarter? How do you know?
  12. (1 point) How many quarters would be required to make a stack as tall as your height?
  13. (1 point) What would the total mass of such a stack be?
  14. (1 point) Could you use your caliper to measure the thickness of a single sheet of paper? To what accuracy? To what precision?
  15. (1 point) Devise a scheme to measure the average thickness of the pages of a book more accurately than using the caliper on a single sheet. Describe and implement your scheme.
