UNIT Kinematics 1. A Displacement DATE Hedizin NAME Scenario Angela is running to the bus 15 meters away. sm lom 15m Using Representations PART A: On the diagram to the right, label Angela's position with zero meters and label the position of the bus door 15 meters. Label the marks between Angela and the bus with appropriate position values Based on the labels along the axis in the diagram above, what direction (left or right) should be labeled positive? Label this direction on the diagram using an arrow (vector). PART If the positive direction was labeled as the opposite direction of what you chose in Part A think about how the locations of the labels for O meters and 15 meters would change. Relabel the diagram at right, with the positive direction pointing the opposite way as in Part A. Include position values along the bottom of the scale. 0 sm How tom number Argumentation PARTG: You are asked to make a claim about the physical meaning of Angela's displacement in Part B. Fill in the blanks below to complete the Claim, Evidence, and Reasoning paragraph. Evidence: When Angela gets to the bus, her position is meters. Angela's initial position was_1_meters. nuer Reasoning: Displacement is equal to the final position minus the initial position. Ar = x-, or Ax = *-* Claim: Therefore, Angela's displacement is meters minus meters which equals meters, number Data Analysis het PART D: How does the displacement in Part C compare to the displacement in Part A? numbe number The part c Her displacement Ts 15 meters PARTE: If Angela ran to the bus and back to where she started, what distance would she travel? Compare that to her displacement. So her displacement is zero, but her distance is double 15 x2 =30m.
