Energy
Core concepts and learning points for this section:
Syllabus Points
Core
- 1.7.1.1 State that energy may be stored as kinetic, gravitational potential, chemical, elastic (strain), nuclear, electrostatic and internal (thermal)
- 1.7.1.2 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
- 1.7.1.3 Know the principle of the conservation of energy and apply this principle to simple examples including the interpretation of simple flow diagrams
Supplement
- 1.7.1.4 Recall and use the equation for kinetic energy Eₖ = ½mv²
- 1.7.1.5 Recall and use the equation for the change in gravitational potential energy ΔEₚ = mgΔh
- 1.7.1.6 Know the principle of the conservation of energy and apply this principle to complex examples involving multiple stages, including the interpretation of Sankey diagrams
