  1. Motion Unit Lesson 6 Monday, December 12, 2011

  2. Today’s Warm-up Tape the following into your journal Complete “Moving Along II”

  3. Moving Along II

  4. Science Standard S8P3. Students will investigate relationship between force, mass, and the motion of objects. Determine the relationship between velocity and acceleration.

  5. Today’s Essential Question How is the motion on a distance-time graph correlate with the same motion shown a speed-time graph?

  6. Daily Goals • Demonstrate knowledge of velocity and distance-time graphs. • Interpret a speed vs. time graph to determine if object demonstrates constant speed, positive acceleration, or negative acceleration. • Compare the speed of a ball rolling down a ramp to the speed of the tumble buggy car.

  7. Toy Race Lab Let’s compare the motion of a tumble buggy to the motion of a ball rolling down a hill. This will be a whole class experiment. Each team must complete their measurement twice. Average the time and report it to teams #7 and 8 Team #1 – Measures the time it takes for a tumble buggy to go from 0 to 1 meter mark. Team #2 -- Measures the time it takes for a tumble buggy to go from 1 to 2 meter mark. Team #3 -- Measures the time it takes for a tumble buggy to go from 2 to 3 meter mark.

  8. Toy Race Lab Let’s compare the motion of a tumble buggy to the motion of a ball rolling down a hill. This will be a whole class experiment. Each team must complete their measurement twice. Average the time and report it to teams #7 and 8 Team #4 – Measures the time it takes for a ball rolling down a ramp to go from 0 to 1 meter mark. Team #5 -- Measures the time it takes for a ball rolling down a ramp to go from 1 to 2 meter mark. Team #6 -- Measures the time it takes for a ball rolling down a ramp to go from 2 to 3 meter mark.

  9. Toy Race Lab Let’s compare the motion of a tumble buggy to the motion of a ball rolling down a hill. This will be a whole class experiment. Each team must complete their measurement twice. Average the time and report it to teams #7 and 8 Team #7 – Compute the speed of the tumble buggy on each leg. Graph the results Team #8 -- Compute the speed of the tumble buggy on each leg. Graph the results

  10. Toy Race Lab Data Distance (meters) Time (seconds)

  11. Observations: Conclusion:

  12. On a distance-time graph, there are two types of graphs.

  13. Constant speed is shown by straight lines on a distance time graph.

  14. A curved line – represents changing velocity OR acceleration a) Curves upward (getting steeper) – object is speeding up b) Curves downward (getting flatter) -- object is slowing down

  15. On a speed-time graph, you will only see straight lines.
