  1. Bell Ringer On a half sheet of paper answer the following in complete sentences: What is the difference between distance and displacement? Compare and contrast speed and velocity. Why is acceleration sometimes negative? How do you find the slope of a line? C’mon. Let’s get to work.

  2. Lab 3.1 Measuring Average Velocity and Average Acceleration in a Mechanical System Page 65

  3. Lab 3.1 Velocity and Acceleration Objectives • Determine average velocity of an object using the slope-intercept method. • Calculate average velocities for specific intervals. • Plot average velocity versus time • Find the presence of acceleration by reading an average velocity graph. Proficiencies • Set up and perform an experiment to measure average linear-velocity Materials • Digital Stopwatch • Masking tape • Toy car • Meter stick

  4. When you get in your lab groups… • Bring your notebook, pencil, and calculator (if you brought it). • Assign roles and write your group members and their roles on the bottom first page of your lab data sheet. • Send your Materials Manager to collect safety glasses (sanitized) and a calculator for your group. • Have your Head Physicist read the Discussion to everyone. Head Physicist makes sure everyone understands the concepts before proceeding with the lab. • Wear your safety glasses AT ALL TIMES and begin. • Lab Instructions will be on your lab table. • Submit 3.1 Data Sheet today.

  5. Page _64_: Lab 3.1 Data, Procedure, and Conclusion • Exit Slip: • Turn in the 3.1 Data Sheet • HWA: • Finish Procedure and Conclusion Questions • Remember to use the given Objectives • Write your answers in complete sentences Procedure • At least 6 numbered steps • Should be easy to follow • May use diagrams Conclusion: • Did you meet your objective? Why or why not? • What possible sources of error could have affected your data? • What did you learn from this lab? • How was your group able to rely on your in your assigned role?
