About This Quiz & Worksheet

This quiz and worksheet assessment tool is designed to help you measure your knowledge of free fall and resistance concepts. You must be able to apply relevant formulas in order to correctly answer each of the questions contained in this quiz.

Quiz & Worksheet Goals

When taking this quiz, you will need to:

  • Determine how far a person would fall in 15 seconds in a given scenario
  • Identify the acceleration of the same person in this scenario
  • Understand the acceleration due to air resistance of the falling person
  • Note the kinetic energy of this person traveling at free fall
  • Give the speed of the person falling after 15 seconds if traveling in free fall

Skills Practiced

  • Problem solving - use acquired knowledge to solve acceleration practice problems
  • Information recall - access the knowledge you've gained regarding acceleration due to free fall
  • Knowledge application - use your knowledge to answer questions about free fall
