Four subject capsules
Physics
- Centripetal acceleration points toward the centre: aᶜ = v²/r.
- Gravitational force depends on the product of masses and inverse square of distance.
- In circular motion, distinguish tangential speed from radial acceleration and identify the force providing the inward resultant.
Chemistry
- Across a period, effective nuclear attraction generally changes atomic size and ionisation behaviour.
- Ionic bonding involves electrostatic attraction after electron transfer; covalent bonding involves shared electron pairs.
- Use electronegativity as a guide, not as a substitute for drawing the bonding structure.
Higher Mathematics
- The tangent at x = a has slope f′(a).
- Stationary points satisfy f′(x) = 0, but classification needs a change-of-sign or second-derivative argument.
- State whether a point is local maximum, local minimum or neither.
Biology
- A gene is a functional unit of hereditary information; an allele is an alternative form of a gene.
- Genotype describes genetic constitution; phenotype is the observable expression shaped by genotype and environment.
- Dominant does not mean more common, stronger or better.
Recall without notes
- What supplies centripetal force in a particular circular-motion example?
- Why is a covalent bond not simply the same as an ionic bond with weaker transfer?
- How do you distinguish a maximum from a minimum?
- Explain dominant versus recessive without using popularity.
Practice and application
- Complete four circular/gravitational problems and draw the force direction in each.
- Predict trend direction for atomic size and ionisation energy in simple cases.
- Solve two tangent questions and two maxima–minima questions.
- Create a genetics vocabulary map: gene, allele, genotype, phenotype, locus.
