Mission WE4: Mechanical Energy

Mission WE4 pertains to the concept of mechanical energy and its relationship to kinetic and potential energy. The mission consists of 36 questions organized into 9 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 define mechanical energy and relate it to the amount of kinetic energy and potential energy.
• The student should be able to analyze a physical situation and identify whether the total mechanical energy of an object is increasing, decreasing or remaining constant.
