Physics: Integration

Syllabus: PC_BK_04 Integration The following description of integration and differentiation is from the website Math is Fun! 🙂 This is most likely all you will need to know about the subject for the FRCA. A one liner explanation for what it is – it is a mathematical method of determining the area under a curve….

Physics: SI units and commonly used derived units

Syllabus: PC_BK_07, PC_BK_08 This page covers commonly used SI units and derived units, an exam favourite! Definitions The acronym for the SI units is SMMACKK – Second, meter, mole, ampere, candela, kilogram and kelvin. Second – time The second (s) is defined by taking the fixed numerical value of the cesium frequency ∆νCs, the unperturbed ground-state hyperfine…

Physics: Physical measurement and calibration

Syllabus: PC_BK_05 This page covers terms like accuracy and precision, drift, hysteresis and calibration and has some videos on how you can explain this succinctly during a physics viva. Definitions Accuracy: The ability of a measurement device to match the actual value of the quantity being measured. Precision: The reproducibility of repeated measurements and a…

Physics: Logarithms and exponentials

Syllabus: PC_BK_03 This page covers what logarithms and exonentials are, then we have a short video on negative exponentials that is a popular viva question for primary and final exams! What are logarithms? They basically answer: How many of one number do we multiply to get another number? How many 2s do we multiply to get 8? Answer: 2 × 2…
