Basic Principles of Energy  

 

Students will be able to:

  • Recognize that energy (and entropy, etc.) are concepts that unify physics, biology, and chemistry, and the same basic physical principles can be applied in all three disciplines
  • Analyze physical systems in terms of energy, identifying the relevant forms of energy
    • Understand chemical energy as electric potential energy (with some kinetic energy thrown in) 
    • Describe chemical energy in terms of PE vs r diagrams  
    • Understand thermal energy as kinetic energy of molecules 
  • Use the Work-Energy Theorem to relate energy to forces
  • Go back and forth between representations of potential energy and the corresponding forces
  • Go back and forth between microscopic and macroscopic descriptions of forms of energy (e.g. understanding thermal energy as kinetic energy of molecules, and chemical energy in terms of electrical interactions)
  • Identify energy transformations within a system
  • Track energy into/out of a system to make sense of energy conservation
