Mission WE5: Force and Energy

Mission WE5 pertains to the concepts of conservative and non-conservative forces and the effect such forces have upon the total mechanical energy when they are doing work. The mission consists of 40 questions organized into 10 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...

Learning Outcomes

  • The student should be able to categorize forces as being conservative or non-conservative and explain the significance of such a categorization scheme.
  • The student should be able to predict whether an object's total mechanical energy would be conserved or not conserved based upon the types of forces which are doing work upon the object.
