NSSCO Physics (6118) case studies
NSSCO Physics (6118) · Put your knowledge to work in context.
NSSCO Physics (subject code 6118) is the Ordinary Level physics qualification taken at the end of Grade 11 in Namibia's senior secondary school system. It is aimed at learners who need a solid grounding in physics either as preparation for AS Level study or as a supporting subject for technical, health and engineering-related pathways, and it is also used by candidates who are returning to study or improving results part-time. The syllabus builds from measurement and units into mechanics, then work, energy, power and pressure, thermal physics, waves, sound and light, electricity and magnetism, and finally atomic and nuclear physics. Assessment mixes multiple-choice items with structured and extended written answers, plus a practical component - either school-based experimental work or an alternative-to-practical written paper, depending on your centre. The NSSCO Physics (6118) case studies are 5 cases and about 3,492 words.
1Zero error and significant figures in a density determination
A learner is asked to identify a small metal cylinder from its density. The top-pan balance gives a mass of 1.92 g.
655 words, about 3 min2Stopping distance for a loaded delivery van
An empty delivery van travels at 14 m/s on a straight, level road. The driver's reaction time is 0.70 s, and the brakes produce a constant deceleration of 6.0 m/s².
668 words, about 3 min3Sizing a pump for a borehole supply
A farm must raise water from a borehole to a storage tank. The water surface in the borehole is 38 m below ground level.
705 words, about 4 min4Resonance tube measurement of the speed of sound
A learner uses a resonance tube, closed at one end, with a tuning fork marked 480 Hz. The first loud resonance occurs with the air column 16.4 cm long and the second with the column 50.8 cm long.
