  1. Average Velocity Lab Lunch Lab Week 1 August 25-29

  2. Average Velocity Lab • Purpose: Figure out a way to make a cart move with an average velocity of as close to 0.200 m/s as possible. Use only the equipment provided. Photogate must be in PULSE mode. • Partial Report: The partial report we want you to write for this lab will contain a title, purpose, diagram, procedure, and results, which will be written very neatly in your lab notebook. You will be graded most heavily on the procedure you write. Check the Physics B web site for information about lab reports.

  3. 1D Video Analysis Lab Lunch Lab Week 2 September 2-5

  4. 1D Video Analysis Lab Purpose:To analyze the motion of objects in motion to determine their velocity and acceleration Instructions: • Open “Logger Pro” software on your computer. • Open the Physics B website in a browser and click on “Lab Video Links” in the menu to the left. Save the video clips to your desktop. • Import the first video into “Logger Pro” • Click on button in lower right to start analyzing the video. Set the origin. Set the scale. • Choose a point on the object to track. Click to place points there for successive frames (frames should advance automatically) • Curve-fit your data using “Logger Pro” tools. Save your work to the desktop. • Repeat steps 3-5 for the remaining video clips. Assessment:As a group, submit your graphs to the web using the N drive “Hand-in” folder. No ‘lab report’ for this lab.

  5. Projectile Lab Lunch Lab Week 3 September 9-11, 2008

  6. Projectile Lab The purpose is to collect data to plot a trajectory for a projectile launched horizontally, and to calculate the launch velocity of the projectile. Using the equipment given, come up with a method to reproducibly launch the projectile horizontally with a consistent speed. Then come up with a procedure to record the distance the projectile falls (the dependent variable) as a function of the horizontal distance it travels (the independent variable). Collect (x,y) data for at least six horizontal distances, and do several trials at each distance to test the reproducibility of your method. Turn in a full lab report, minus the hypothesis. Make sure you do a thorough job on the following: • a table of data • a graphof the trajectory • a calculation of the launch velocity of the ball obtained from the data

  7. 2D Video Analysis Lab Week 4 Lunch Lab September 16-18, 2008

  8. Login: hslc210lab 2D Video Analysis Lab The purpose of the lab is to demonstrate the independence of motion in two dimensions. Open Mr. Perkins’ 3rd period “Projects” folder and save the two video clips to the desktop. Open Logger Pro and import video “horizprojectile.avi.” Mark the position frame by frame and curvefit x vs. t and y vs. t for the fall. Type the following information in a textbox, then save • The horizontal and vertical equations of motion with curvefit information. • Determine and list ‘g’ and ‘vox’ from the curvefit. Import video clip “balltossproj.avi.” Set the origin at the position of the ball on the first frame. Analyze the same as the other clip except this time you also determine voy and mark with an oval the position on the graph where vy = 0 Save both to the desktop, then Mr. Perkins’ folder

  9. Open. Repeat above analysis. • Submit both graphs to Mr. Perkins’ 3rd or 6th period “Hand-in” folder

  10. Newton’s Second Law Week 5 Lunch Lab September 22-26, 2008

  11. Newton’s 2nd Law Lab • Purpose: to compare experimental acceleration values obtained using measurements of distance and time to those obtained theoretically with Newton’s 2nd Law. It is important to take good, clear data during this lab, since you probably won’t be able to analyze all of the data right away. The full, typed lab report is due on October 13. Record data and observations in your lab notebook, but turn in a full, typed lab report for a grade. • Hypothesis: Your hypothesis can be a general statement regarding how well you think your experimental and theoretical accelerations will agree. If you think they will be different, see if you can predict how they will differ. • Theoretical Background: Relevant kinematic and Newton’s Law equations. • Equipment: Make a list from what you use. • Procedure: Brief step-by-step procedure. Make sure you include a diagram of your experimental set-up! • Data: Tabulate the data necessary to determine acceleration by the two methods. Your teacher will help you decide what data to record during the pre-lab session. Leave room to perform multiple trials for two different experiments. • Calculations:Calculations of experimental acceleration (from kinematics) and theoretical acceleration (from Newton’s Laws) must be done and shown clearly. A free body diagram must appear as part of the Newton’s Laws analysis! • Results: What are your acceleration values? • Analysis: Was your hypothesis right? How close are your experimental and theoretical values? What are some sources of error? • Conclusion: Was the purpose fulfilled? What did you learn?
