HSC Physics case studies
HSC Physics · Put your knowledge to work in context.
HSC Physics is a Stage 6 science course within the Higher School Certificate, the senior secondary credential in New South Wales. NESA, the NSW Education Standards Authority, sets the syllabuses, assessments, teaching and school standards for all schools in NSW, and it describes the HSC as a world-class credential that helps young adults on the path to work, training and further education. The HSC Physics case studies are 5 cases and about 1,813 words.
1Projectile Launch Over a Fence
A ball is launched from ground level at 18 m/s at 40° above the horizontal toward a 2.4 m high fence whose base is 22 m from the launch point. Air resistance is negligible.
384 words, about 2 min2Circular Motion on a Banked Curve
A car of mass 1200 kg rounds a frictionless banked curve of radius 45 m at 20 m/s. The banking angle is set to 25°.
342 words, about 2 min3Transformer Efficiency Under Load
A step-down transformer has 1200 turns on the primary and 60 turns on the secondary. It is connected to a 240 V RMS AC mains supply and delivers power to a 12 Ω resistive load.
377 words, about 2 min4Photoelectric Effect and Intensity
A metal surface has a work function of 2.3 eV. It is illuminated first with light of wavelength 450 nm at low intensity, then with light of wavelength 300 nm at the same intensity, then with 450 nm light at ten times the intensity.
343 words, about 2 min5Magnetic Braking of a Falling Magnet
A strong bar magnet is dropped through a vertical copper tube of length 1.2 m. A student observes that the magnet falls noticeably slower than a magnet dropped through a cardboard tube of the same length, and that the copper tube becomes slightly warm.
