This subject report is listed under Physics in the 2015 examination archive. The catalogue session is May 2015. The information below helps you identify the document before opening the complete PDF. Subject, year and session labels come from the archive catalogue; the original cover remains the reference if a label differs. A file is not automatically suitable for your current syllabus simply because its subject name matches.
For coursework research, read this document as a reference rather than a template to submit. Notice how the question, evidence and explanation connect. If a paired commentary or subject report is available, compare it with the original work instead of assuming a polished essay received a particular mark. Historical examples may belong to an earlier assessment framework.
The public preview contains file information and, where reliable text extraction is available, a limited opening excerpt.

The range and suitability of the work submitted
The highly diverse topics chosen by candidates represent many domains of physics:
mechanics is popular (motion in gravitational field, collisions, dynamics, rotational motion on
an incline, energy exchanges, mechanical properties of materials, tensile strength of rope,
oscillations of all types, aero and hydro- dynamics), interference of sound waves, waves,
music and sound, radio wave propagation, effect of air pressure on rolling friction and on
elasticity of balls, effect of temperature on the physical properties of materials, emissivity of
an incandescent lamp filament, astrophysics, behavior of light in aqueous salt concentrations,
music and sound, physics of sports (tennis, squash, surfing waves, trampoline), photovoltaic
cells, magnetism, electromagnetic induction, water mills and heat engines , are some
examples.
The initiative, creativity, determinati on, dedication and perseverance of a large number of
candidates must be recognized. Many facets of scientific investigation are given.
The range of marks varies from excellent to, very rarely, elementary. Most essays fall into the
middle range with few exc eptional and few poor essays. Typically essays are experimental in
their approach with some examples of data- based essay, simulation and survey type of
essay.
Good error analysis distinguishes excellent essays and demonstrates insight into the
underlying physics concepts and without irrelevant or marginally relevant commentary. They
include a specific, clear, highly focused and detailed investigation with a personal touch and
originality. Very good essays have a crisp theoretical or conceptual summary coupl ed to a
carefully designed research question and study.
In some weak essays the physics is incomplete. In some cases the physics applied by
candidates is so far off reality that it weakens or invalidates the work (e.g. failing to recognize
rotational energ y, moment of inertia, cases of non- uniform acceleration). Perhaps not in the
