Bernoulli's Principle - Questions
The Bernoulli's Principle Concept Builder is comprised of 38 questions. The questions are divided into 16 different question groups and spread across three different activities. 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.
The questions and question groups are organized into three different activities. The activities are differentiated as follows:
- Bernoulli Effects Question Groups 1-6: Students analyze six common examples of the Bernoulli effect (airplane wing, spinning golf ball, spinning baseball, etc.) and use Bernoulli's principle to determine where the pressure is greatest and predict the effect that this has upon the object.
- Pressure Meters Question Groups 7-10: Students analyze fluid flow in a horizontal tube that narrows or widens in order to identify the location with the greatest speed and the location with the greatest pressure. They match their findings to a diagram displaying a set of attached Venturi tubes or a manometer.
- Bernoulli Thinking Question Groups 11-16: Students use Bernoulli's equation (and the continuity equation) to compare the velocity, height, and pressure at two locations along an ascending or descending flow tube.
The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which activity is most appropriate for their classes. We recommend doing all three activities.
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.
