Minds On - Work and Energy
The Work and Energy Minds-On module consists of various missions (assignments) that address such topics as work, power, kinetic and potential energy, and the relationship between the mechanical energy of an object and the work done upon or by it. The missions and the corresponding objectives are listed below. Tap a mission's name to begin.
Activities
Mission WE1 pertains to the concept, the meaning, and the mathematics of work. You should be able to recognize examples and non-examples of work and distinguish between positive and negative work. The mission consists of 39 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 ...
Mission WE10 focuses on the mathematical relationships between the work done by non-conservative forces and the kinetic and potential energies of an object. Energy formulas will have to be used to calculate such quantities as work, kinetic energy, potential energy, speed, and height. The mission consists of 16 questions organized into 8 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcome for this mission is ...
Mission WE2 pertains to the concept of mechanical power. You should know the definition of power, the unit for power, the meaning of a rate quantity, the mathematics of power, and the distinction between power and work. The mission consists of 32 questions organized into 8 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...
Mission WE3 focuses on the contrasting meaning of kinetic energy and potential energy. You should be able to disinguish between the two modes of energy and be able to recognize the presence of either form and the manner in which it changes. 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 ...
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 ...
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 ...
Mission WE6 focuses on the use of work-energy bar charts to describe the energy changes that are occuring for an object from the initial state to the final state of motion. 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 outcome for this mission is ...
Mission WE7 pertains to situations in which the mechanical energy of an object is conserved. You should understand the conditions under which mechanical energy is and is not conserved and apply conservation principles to such situations. The mission consists of 32 questions organized into 8 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...
Mission WE8 requires that you use energy relationships and formulas to determine the kinetic and potential energies of an object at varying locations and to compute speeds and heights at such locations. The mission consists of 16 questions organized into 8 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...
Mission WE9 focuses on situations in which the mechanical energy of an object is transformed into non-mechanical energy (or vice versa). You should know the conditions under which such energy transformations occur. 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 ...
