5 Final: There may be conceptual and will be problem based questions involving vectors. The problem based questions will require students to demonstrate appropriate use of vectors and vector operations. For CSLO 4 a possible problem set related to vectors might be: 1. We can order events in time. For example, event b may precede event c but follow event a, giving us a time order of events a, b, c. Hence there is a sense of time, distinguishing past, present, and future. Is time a vector therefore? If not, why not? 2. Consider two displacements, one of magnitude 3 meters and another of magnitude 4 meters. Show how the displacement vectors may be combined to get a resultant displacement of magnitude (a) 7 meters, (b) 1 meter, and (c) 5 meters. 3. Given two vectors a 4iˆ3ˆj and b 6iˆ8ˆj, find the magnitude and direction of a, of b, of a + b, of b - a, and of a - b. 4. Find the sum of the vector displacements of c and d whose components in miles along three perpendicular directions are cx = 5.0, cy = 0, cz = -2.0; dx = -3.0, dy = 4.0, dz = A vector d has a magnitude of 2.5 meters and points due north. What are the magnitudes and directions of the vectors (a) - d, (b) d /2.0, (c) -2.5 d and (d) 4.0 d? 6. A vector a of magnitude ten units and another vector b of magnitude six units point in directions differing by 60 o. Find (a) scalar product of the two vectors and (b) the vector product of the two vectors. 7. Given vector a in the +x-direction, vector b in the +y-direction, and the scalar quantity d: (a) What is the direction of a X b? (b) What is the direction of b X a? (c) What is the direction of b /d? (d) What is the magnitude of a b? 8. Two vectors are given by A3.0iˆ5.0 ˆj and B 2.0iˆ 5.0 ˆj. Find (a) A X B, (b) A B, and (c) ( A + B ) B. 9. Three vectors are given by A 3iˆ3ˆj2kˆ, B iˆ4ˆj2kˆ and C 2iˆ2ˆjkˆ. Find (a) A ( B X C ), (b) A ( B + C ) and (c) A X ( B + C ). Method of Evaluation/Grading: An A-level student will have all of the correct physical concepts and correctly apply the mathematics. The structure of the solutions is correct and details present. When multiple concepts are involved an A-level student will include all necessary concepts. A-level student work on problem sets/quizzes is characterized by clear, coherent, thorough, accurate communication of the underlying physical concepts and mathematical principles. On labs A- level student work is characterized by correctly following directions, constructively participating and contributing to group activities, and thorough, detailed, accurate write-ups that cover the physics principles explored. A-level student work on midterms and the final is characterized by clear, coherent, thorough, accurate communication of the underlying physical concepts and mathematical principles. A C-level student might have the correct physical concept but not apply the mathematics correctly. The structure of the solution could be correct but the details flawed. When multiple concepts are involved a C-level student might Form Revised Page 5 of 8

6 have some, but not all of the conceptual knowledge. C-level student work on problem sets/quizzes is mostly characterized by clear, coherent, thorough, accurate communication of the underlying physical concepts and mathematical principles. On labs C-level student work is characterized by correctly following directions, constructively participating and contributing to group activities, but details, thoroughness and accuracy may be missing in their write-ups regarding the physics principles explored. C-level student work on midterms and the final is mostly characterized by clear, coherent, thorough, accurate communication of the underlying physical concepts and mathematical principles.
