Vector Direction - Exercise

The Vector Direction Concept Builder is comprised of 54 questions. The questions are divided into 18 different question groups with three questions in each group. Questions in the same group are similar to one another; they may include three different vectors located in the same quadrant or three different vectors, each being 15° from an axis. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.

There are three activities which a student can do in this Concept Builder. Those activities are differentiated as follows:
 
  • Counter-Clockwise from East: Question Groups 1-6; students are given a diagram of a vector and drag a protractor into position in order to measure an angle and express the direction of the vector as a counter-clockwise angle of rotation from due east.
  • Rotation Angle from Nearest Axes: Question Groups 7-12; students are given a diagram of a vector and drag a protractor into position in order to measure an angle and express the direction of the vector as the angle of rotation from one of the two nearest axes.
  • Convention Conversions: QuestionGroups 13-18; students are given the direction of a vector in one of the two conventions and must do some spatial/mathematical reasoning in order to express the directoin in the other convention.

The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which activity or activities are most appropriate for their classes. 

The Physics Classroom grants teachers and other users the right to print these questions for private use. Users are also granted the right to copy the text and modify it for their own use. However, this document should not be uploaded to other servers for distribution to and/or display by others. The Physics Classroom website should remain the only website or server from which the document is distributed or displayed. We also provide a PDF that teachers can use under the same conditions. We have included a link to the PDF near the bottom of this page.
