PHYSICS EXAMINATIONS – 2013 Bruce Walsh Chief Assessor
REMINDERS • Study design and textbooks • Examiners report • VASS system • SSMS • On line marking
GENERAL ADVICE • Mark allocation • Writing implements • Multiple attempts • Logical set out of working
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
GENERAL ADVICE • Show numbers substituted into formulae • Formulae (including derived) must be correct • Calculators – sci mode, no truncation • Rounding
GENERAL ADVICE • Answers as simplified decimals • Significant figures • Vectors should originate from point of application • Realistic answers • A
SPECIFIC CONCERNS • Vectors in Newton’s second & constant acceleration equations • Connected bodies • Energy conversion and conservation • Unit conversions • More complex projectile motion
SPECIFIC CONCERNS • Series circuits • Confusion with Faraday’s and Lenz’s laws • Understanding of flux and EMF • Photoelectric effect • Path difference in interference • Distinction between matter & electromagnetic radiation
