Case Studies: Impulse and Force

The Case Studies: Impulse and Force Concept Builder is comprised of a bank of 16 questions that are delivered to the learner across two different difficulty levels. The 16 questions are organized into eight groups of two questions each. All questions target the learners ability to use the impulse-momentum change equation to analyze two contrasting collisions. Learners must identify the variable - velocity change, time, or mass - that is altered from one collision to the other. They must also determine which collision involves the greatest momentum change, impulse, and force. 

The two difficulty levels differ only in terms of the number of contrasting collisions that must be analyzed. They can be summarized as follows:
 

• Master Difficulty Level: Question Groups 1-4
• Wizard Difficulty Level: Question Groups 1-8

The questions and images used in this Concept Builder are shown below. Teachers are encouraged to view the questions in order to judge which difficulty level is 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 this 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.
