I need you to help design a simulation that will enhance students conceptual understanding of relative velocity in 2-D. Studies and / or experience show that students have great difficulty in distinguishing velocity and relative velocity in 2-D. Consequently it becomes a rather difficult task for students to translate the information into correct vector diagrams and so perform vector addition and subtraction and / or use sine and cosine rules to solve triangles. Many students have difficulties in interpreting the language of vectors. For instance between the case when the wind is blowing "north" as contrasted to the wind blowing from "the north". The simulation will be used to teach this topic to introductory physics students at Mukuba University. I will appreciate if the design can be done, say, by early October.
