Case Studies - Circular Motion - Questions
The Case Studies - Circular Motion Concept Builder is comprised of 36 questions. The questions are divided into 12 different Question Groups. Questions in the same group are rather similar to one another. 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 different activities that can be engaged in through the Concept Builder. Each activity focuses on a different variable relationship. The activities can be differentiated as follows.:
- Speed Activity: Groups 1-4 The effect of radius and period on speed.
- Acceleration Activity: Groups 5-8 The effect of speed and radius on acceleration.
- Net Force Activity: Groups 9-12 IThe effect of mass, speed, and radius on net force.
The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which activities are most appropriate for their classes. We recommend providing students two or more options.
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.
