1. PHYSICS EXAMINATION – 2014 Bruce Walsh Chief Assessor

2. REMINDERS  Study design and textbooks  Examiners report  VASS system  SSMS  On line marking

3. GENERAL ADVICE  Mark allocation  Writing implements  Multiple attempts  Logical set out of working

4. GENERAL ADVICE  Explanations must address specific question. Writing everything can lead to contradictions. Dot points good. Diagrams and formulae can help.  Show working  Use unit in answer box

5. GENERAL ADVICE  Show numbers substituted into formulae  Formulae (including derived) must be correct  Calculators – sci mode, no truncation  Rounding

6. GENERAL ADVICE  Answers as simplified decimals  Significant figures  Vectors  Realistic answers  Scales on axes AAAA

7. SPECIFIC CONCERNS  Connected bodies  Energy conversion and conservation  More complex projectile motion  Apparent weightlessness  Modulation  Explaining direction of induced current

8. SPECIFIC CONCERNS  Operation of transformers in transmission system  Series circuits  Explaining aspects of photoelectric effect  Path difference in interference  Electron and X-ray diffraction patterns

9. SPECIFIC CONCERNS  Electron energy level diagrams and associated emissions and absorptions  Wave nature of matter and electron energy levels
