Overview of IB Physics Paper 3 and Its Markscheme

Purpose and Structure of Paper 3

The IB Physics Paper 3 is designed to evaluate candidates' understanding of the core topics and options beyond the core syllabus. Unlike Papers 1 and 2, which are predominantly multiple-choice and short-answer questions, Paper 3 emphasizes extended problem-solving, data analysis, and application of concepts to real-world scenarios. It typically consists of:

• Section A: Multiple-choice questions
• Section B: Structured questions, often requiring calculations
• Section C: Extended responses or data-based questions

The options included vary depending on the candidate's choice, such as Astrophysics, Engineering Physics, or Imaging. The May 2013 exam covered specific options, with the markscheme tailored to these.

Importance of the Markscheme

The markscheme for Paper 3 is not just a grading tool but also a reflection of examiners' expectations regarding candidate understanding and reasoning. It delineates:

• The allocation of marks for different question parts

Markscheme Highlights:

• Recognition of the need to apply the centripetal force and gravitational force balance:

\[

\frac{GMm}{r^{2}} = \frac{mv^{2}}{r}

\]

\[

r = \frac{6.67 \times 10^{-11} \times 5.97 \times 10^{24}}{(3200)^2}

\]

• Deducting Earth's radius to find the satellite's height:

\[

h = r - R_{earth}
