NSSCAS Physics (8225) case studies
NSSCAS Physics (8225) · Put your knowledge to work in context.
The NSSCAS Physics (8225) is the Advanced Subsidiary level physics qualification within Namibia's senior secondary certificate framework, normally taken in Grade 12 after the ordinary-level (NSSCO) science subjects. It suits learners who intend to move into engineering, physical sciences, health sciences, mining and energy technology, or science teaching, and who need a demonstrated grasp of physics with mathematical reasoning rather than a descriptive survey. The NSSCAS Physics (8225) case studies are 5 cases and about 3,623 words.
1Trolley on an Incline: Is the Shortfall Due to Friction?
A student investigates whether a trolley rolling down a ramp obeys a = g sin θ. The ramp is set at θ = 8.0° ± 0.5°.
