Hit-and-Stick Collisions - Law Enforcement

The Hit-and-Stick Collisions - Law Enforcement Concept Builder is comprised of a bank of 24 questions that are delivered to the learner across three different difficulty levels. All three difficulty levels use the same 24 questions. They are only different in terms of the number of questions that must be answered at each level. Questions are grouped and chosen at random from within the same group. If a learner misses a question within Question Group 1, then another question within the same group will be presented to the learner at a later time.

The three difficulty levels in this Concept Builder are differentiated as follows:
 
  • Apprentice: 4 Question Groups (with 6 questions each)
  • Masters: 8 Question Groups (with 3 questions each)
  • Wizard: 12 Question Groups (with 2 questions each)

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