NCEA Level 2 Physics case studies
NCEA Level 2 Physics · Put your knowledge to work in context.
NCEA Level 2 Physics is the Level 2 physics offering within New Zealand's National Certificate of Educational Achievement, administered by NZQA. It is designed for secondary learners who want to build a deeper understanding of the physical world - how forces and motion, matter and energy, and space and time can be described by general laws. Note that Physics is no longer available at Level 1; Physics, Earth and Space Science is the Level 1 subject on the New Zealand Curriculum. At Level 2, Physics includes both internally assessed standards and external assessment. The NCEA Level 2 Physics case studies are 5 cases and about 2,834 words.
1Cart on a Ramp: Missing Energy
At a school laboratory, a student releases a 2.40 kg cart from rest at the top of a ramp that is 1.80 m long and inclined at 25° to the horizontal. Using conservation of energy, the student predicts the speed at the bottom will be 3.86 m/s.

A student investigates a bouncing ball using a force plate and a motion sensor. A 0.050 kg rubber ball is released from rest at a height of 1.20 m above the plate.
619 words, about 3 min3Dim Lamp in a Series–Parallel Circuit
A student builds a circuit to investigate why a lamp is dim. The battery has an emf of 6.0 V and an internal resistance of 0.50 Ω.
