Understanding Motion: Distance, Displacement, Speed, and Velocity Activities

DESCRIPTION

In this lesson, students will explore key concepts in physics regarding motion and forces, focusing on the distinctions between distance and displacement, as well as speed and velocity. The class will start with a reflective catalyst activity, followed by group exercises that encourage active thinking through mapping walking directions. Students will engage in various practice problems to apply their knowledge of scalars and vectors. As they work collaboratively, they will be preparing for assessments and incorporating hands-on learning techniques to reinforce key principles.

Presentation Transcript

  1. Unit 2 (Motion & Forces), Day 1 Distance vs. Displacement, Speed vs. Velocity

  2. Student Entrance • Pick up 4 papers • Catalyst, Walking Directions (Distance),Physics Reference Sheet, Homework • Begin Catalyst • Silent activity • Respond to questions on the CATALYST sheet • Use complete sentences • Will be turned in to Mrs. Larkin

  3. Agenda • 10 min: Catalyst (Exam Reflection) • 25 min: Activity (Distance Activity, Displacement Activity) • 25 min: Notes (Dist. vs. Disp., Scalar vs. Vector) • 7 min: Break • 8 min: Practice (Distance vs. Displacement) • 10 min: Notes (Speed vs. Velocity) • 13 min: Practice (Speed) • 2 min: Homework (Speed vs. Velocity)

  4. Collect Catalyst

  5. Announcements • If you were absent Monday/Tuesday, I need your labs! • Students must take exam by Thursday at 4:00 PM • Otherwise you will receive a ZERO in the gradebook • Period 1-3 • Aidan Mobley • Brie Quinones • Period 2-4 • Robbie Schraer • Period 6-8 • Bianca Covarrubias • Jasson Montenegro • SiriKhalsa • Period 9-11 • Lauren Lopez

  6. Walking Directions (Distance) • Follow the directions on the worksheet • Stay in the courtyard • Everyone should do their own steps and turns • 5 minute activity • Be quick and efficient • Focus on what you are doing, not on others

  7. Think-Pair-Share • Mrs. Larkin’s Example

  8. Think-Pair-Share • Think: • Recall your journey • Map it out on the dots as Mrs. Larkin did • Pair: • Compare journeys with your group members • Share: • 3 people called at random to draw their journeys

  9. Walking Directions (Displacement) • NEW DIRECTIONS! • Follow the directions on the worksheet • Stay in the courtyard • Everyone should do their own steps and turns • 5 minute activity • Be quick and efficient • Focus on what you are doing, not on others

  10. Think-Pair-Share • Think: • Recall your journey • Map it out on the dots as Mrs. Larkin did • Pair: • Compare journeys with your group members • Share: • 3 people called at random to draw their journeys

  11. Think-Pair-Share • Mrs. Larkin’s Example

  12. Collect BOTH Walking Directions • All that you should have left • White homework worksheet • Pink physics equation sheet

  13. Distance vs. Displacement • Notebook

  14. Distance vs. Displacement • Draw small Venn Diagram (about size of hand) • Talk to your group: • 2 similarities for distance & displacement • 1 difference for distance & displacement

  15. Distance vs. Displacement • Distance: how much the object has moved • Displacement: how far object is from its starting point

  16. Distance vs. Displacement • Notebook

  17. Scalar vs. Vector • Scalar: measurement , no direction • To represent a scalar, use a letter • Distance: d • Time: t • Speed: v

  18. Scalar vs. Vector • Vector: measurement WITH direction • To represent a vector, use a letter & arrow • Displacement: x or y • Velocity: v • Acceleration: a

  19. Scalar vs. Vector • Why x or y for displacement? +y (vertical) FALLING DOWN ALONG THE GROUND -x (horizontal) +X • Memory Trick: • H is before V, just • like X is before Y -y

  20. BREAK • 7 minutes • Must be seated, otherwise TARDY

  21. Practice • Whiteboards • 60 seconds: group name • Work with your group • Do not lose markers • Try to not show your answers to other groups!

  22. Practice • Mrs. Larkin runs forward 10 feet. She then turns around and runs back 7 feet. What distance did she run?

  23. Practice • Mrs. Larkin runs forward 13 feet. She then turns around and runs back 6 feet. What displacement did she run?

  24. Practice • Shadow runs 3 meters east, then 2 meters north, then 3 meters west. What distance did she run?

  25. Practice • Shadow runs 4 inches north, then 5 inches east, then 4 inches south. What displacement did she run?

  26. Practice • Ms. Parsons drives to and from Da Vinci Design, which is located 5 miles from her house. • A. What is the total distance she drives every day? • B. What is her displacement every day?

  27. Practice • La Luz runs a complete circle around the classroom. What displacement did she run? (Use feet)

  28. Practice • La Luz and Shadow are racing each other around a circular track. The track is 500 meters around and 159 meters across. La Luz gets tired and stops halfway around. Shadow finishes the race. • A. Who has the greater displacement? • B. By how many meters? 500 meters around 159 metersacross

  29. Practice • La Luz and Shadow are racing each other around a circular track. The track is 500 meters around and 159 meters across. La Luz gets tired and stops halfway around. Shadow finishes the race. • A. Who ran the greater distance? • B. By how many meters? 500 meters around 159 metersacross

  30. Figuring Out an Equation • Here are some units for speed: • Miles per hour (mi/h) • Kilometers per hour (km/h) • Meters per second (m/s) • Feet per second (ft/s) • What do all the numeratorshave in common? • What do all the denominatorshave in common?

  31. Speed vs. Velocity • Notebook

  32. Speed vs. Velocity Speed (SCALAR) is the total distancetraveled in a certain amount of time.

  33. Speed vs. Velocity Velocity (VECTOR) is the displacement (change in position) that occurs in a certain amount of time.

  34. Practice - Whiteboards • Running 59.8 miles in 2 hours When finished with whiteboards, get this problem into notebooks

  35. Practice - Whiteboards • Running 150.6 kilometers in 3 hours When finished with whiteboards, get this problem into notebooks

  36. Practice - Whiteboards • Running 33.75 meters in 2.5 seconds When finished with whiteboards, get this problem into notebooks

  37. Practice - Whiteboards • Running 21.65 feet in 0.5 seconds When finished with whiteboards, get this problem into notebooks

  38. Physics Reference Sheet Speed: Velocity:

  39. Homework • Unit 2, Day 1 – Homework Worksheet for Speed & Velocity • Due FRIDAY, SEPTEMBER 27TH • Look at the homework on projector • If there is extra time, students can work on this before leaving
