Physics Level 4 study guide
Physics Level 4 · Work through your exam, one topic at a time.
National 5 Practical Cookery is a Scottish national qualification in the senior phase of secondary school, delivered by centres and awarded nationally. It suits learners who want to develop practical food preparation and cookery skills alongside the knowledge that underpins safe, hygienic and organised work in a kitchen. The course is assessed in two components. A question paper tests the knowledge and understanding side of cookery, and a practical activity requires candidates to plan, prepare, cook and serve dishes under timed conditions, with marks awarded for techniques, cookery processes, tasting and seasoning, and service details. From session 2026-27 the assignment has been removed; the question paper carries 35 marks and the practical activity 65 marks, and the course has the code C885 75. Preparation should be built around both halves. Topics on this exam: Question paper and Practical activity. The Physics Level 4 study guide has 2 sections and about 744 words.
01Mastering the Physics Level 4 Question Paper
The written paper tests whether you can move fluently between words, symbols, graphs and numbers. Expect questions on kinematics and dynamics (Newton's laws, momentum, circular motion), energy and power, waves and optics, electricity and magnetism, thermal physics, and modern physics ideas such as photoelectric effect and radioactive decay. You must know definitions precisely, be able to rearrange equations, and interpret gradients and areas under graphs. Be secure with SI units and prefixes, significant figures, and uncertainty notation.

The practical component assesses whether you can plan a valid experiment, take reliable readings, process data and evaluate uncertainty. You should be able to identify independent, dependent and control variables, choose suitable apparatus, and describe a method that another student could repeat. Familiar contexts include investigating Ohm's law, Hooke's law, acceleration down a ramp, the period of a pendulum, and the refraction of light through a block. Know the difference between precision and accuracy, and between random and systematic error.

- FlashcardsSI base units. The seven base units are kilogram, metre, second, ampere, kelvin, mole and candela.
- Cheat sheetDimensional analysis check: every term in an equation must reduce to the same base units (kg, m, s, A, K, mol, cd); a mismatch signals an algebra error before any numbers are substituted.
- Key termsscalar. A quantity that has size only, with no direction.
- Study planBuild a one-page formula sheet for mechanics and waves, deriving each equation from its defining relation rather than copying it.
- Common mistakesUnder time pressure candidates treat the unit as decoration and copy the number straight from the calculator; they also memorise formulas without tracking which quantity each symbol represents.
