Learn how to determine a runner's velocity by analyzing distance vs. time graphs, identifying velocity changes, and interpreting positive versus negative velocities. Explore concepts like karma and time intervals of zero velocity. Engage in a graphing lab to calculate slopes and apply the scientific method in your report. Finish your lab efficiently with the given rubric. Don't miss the upcoming quiz on speed, velocity, and acceleration.

GOAL: BECOMING SCIENTIFICALLY LITERATE DO NOW: 10-4-2010 Which runner has the greater velocity? I can analyze a distance vs. time graph to Determine where velocity changes Find the velocity of a runner See the difference between a positive velocity and a negative velocity VOCABULARY: Karma,
At which point in time does Aaron’s velocity change? At which time intervals is Aaron’s velocity zero? What is the difference between the velocity between 6-8 seconds and 9-11 seconds?
GRAPHING LAB DATA: • Your graph needs to include: • Graph title • Axis titles • Evenly spaced axis • 2 slopes: CALCULATE EACH SLOPE
USE THE SCIENTIFIC METHOD – LAB RUBRIC – TO FINSIH YOUR REPORT!! Title: Velocity Lab (Name, Partner’s Names, Class, Date) Purpose: Hypothesis: If the runner’s distance decreases, then _____ because _____ (Remember d/t =d/t) Materials: Procedure: Results: (You can rewrite your data table on another sheet of paper. Include your graph) Conclusion: LAB REPORT DUE TOMORROW – TUESDAY – 10/5 QUIZ ON FRIDAY (speed, velocity, acceleration, Velocity Lab)
