Unit 2 (Motion & Forces), Day 1 Distance vs. Displacement, Speed vs. Velocity 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 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) Collect Catalyst 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 Period 2-4 Robbie Schraer Period 6-8 Aidan Mobley Brie Quinones Bianca Covarrubias Jasson Montenegro Siri Khalsa Period 9-11 Lauren Lopez 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 Think-Pair-Share Mrs. Larkin’s Example 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 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 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 Think-Pair-Share Mrs. Larkin’s Example Collect BOTH Walking Directions All that you should have left White homework worksheet Pink physics equation sheet Distance vs. Displacement Notebook 9/25 or 9/26 UNIT 2 (MOTION & FORCES), DAY 1 • Distance vs. Displacement 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 Distance vs. Displacement Distance: how much the object has moved Displacement: how far object is from its starting point Distance vs. Displacement Notebook 9/25 or 9/26 UNIT 2 (MOTION & FORCES), DAY 1 • Distance vs. Displacement • Scalars vs.Vectors Scalar vs. Vector Scalar: measurement To , no direction represent a scalar, use a letter Distance: d Time: t Speed: v Scalar vs. Vector Vector: measurement WITH direction To represent a vector, use a letter & arrow Displacement: x or y Velocity: v Acceleration: a Scalar vs. Vector Why x or y for displacement? +y(vertical) -x Memory Trick: • H is before V, just like X is before Y F A L L I N G D O W N -y ALONG THE GROUND +X (horizontal) BREAK 7 minutes Must be seated, otherwise TARDY Practice Whiteboards 60 seconds: group name Work with your group Do not lose markers Try to not show your answers to other groups! Practice Mrs. Larkin runs forward 10 feet. She then turns around and runs back 7 feet. What distance did she run? Practice Mrs. Larkin runs forward 13 feet. She then turns around and runs back 6 feet. What displacement did she run? Practice Shadow runs 3 meters east, then 2 meters north, then 3 meters west. What distance did she run? Practice Shadow runs 4 inches north, then 5 inches east, then 4 inches south. What displacement did she run? 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? Practice La Luz runs a complete circle around the classroom. What displacement did she run? (Use feet) 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 meters across 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 meters across 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 numerators have in common? mi h km h m s What do all the denominators have in common? ft s Speed vs. Velocity Notebook 9/25 or 9/26 UNIT 2 (MOTION & FORCES), DAY 1 • Distance vs. Displacement • Scalars vs.Vectors • Speed vs.Velocity Speed vs. Velocity Speed (SCALAR) is the total distance traveled in a certain amount of time. Speed vs. Velocity Velocity (VECTOR) is the displacement (change in position) that occurs in a certain amount of time.
