Energy

What the syllabus asks of you

• State that energy may be stored as kinetic, gravitational potential, chemical, elastic (strain), nuclear, electrostatic and internal (thermal)
• Describe how energy is transferred between stores during events and processes, including examples of transfer by forces (mechanical work done), electrical currents (electrical work done), heating, and by electromagnetic, sound and other waves 4 Recall and use the equation for kinetic energy 1 mv2 / Ek = 2 5 Recall and use the equation for the change in gravitational potential energy ∆Ep = mg∆h
• Know the principle of the conservation of 6 Know the principle of the conservation of energy and apply this principle to simple energy and apply this principle to complex examples including the interpretation of simple examples involving multiple stages, including flow diagrams the interpretation of Sankey diagrams
