In IB Physics First Assessment 2016, describing fields is a subtopic of Topic 10, fields. This subtopic has the following understandings associated with it.

  1. Gravitational fields
  2. Electrostatic fields
  3. Electric potential and gravitational potential
  4. Field lines
  5. Equipotential surfaces

In this part of the analysis, I am particularly interested in “What is the frequency distribution of the questions concerning describing fields understandings?”

Frequency distribution of questions by describing fields for HL

Between 1999-2023

For the entire dataset for HL, more than two-thirds of the questions came from electric potential and, gravitational potential and electrostatic fields. Gravitational fields was barely assessed. A quarter of the questions came from equipotential surfaces.

Figure 1

Between 2016-2023

Between these years, half of the questions came from electrostatic fields. Gravitational fields was the least emphasized understanding.
