Trap of the day
Centrifugal force is a pseudo-force in the rotating frame; the real inward force is centripetal. Don’t mix frames.

In v² = u² + 2as, a is negative for deceleration — keep the sign or the stopping distance comes out wrong.

Molarity is per LITRE of solution (not solvent) and changes with temperature; molality doesn’t.

Chemistry · Thermodynamics
Spontaneity is set by ΔG, not ΔH: an endothermic reaction is still spontaneous if TΔS outweighs ΔH.

Nernst 0.059/n uses log₁₀ at 298 K. Using ln double-counts the 2.303 factor.

Monohybrid F₂ = 3:1, dihybrid = 9:3:3:1 — but only for independently assorting, UNLINKED genes.
A test cross is with a homozygous recessive (reveals genotype); a back cross is with either parent. Not the same.
Biology · Respiration
Glycolysis nets 2 ATP (4 made − 2 used) and occurs in the cytoplasm, not the mitochondrion.
Physics · Optics
Mirror/lens sign convention: distances against the incident light are negative. A dropped sign flips real ↔ virtual.
Physics · Modern
Photoelectric emission depends on FREQUENCY, not intensity — below threshold frequency, no emission however bright.
Physics · Units
Convert km/h → m/s with ×5/18 (not 18/5). Mixing the factor inverts kinematics answers.
Chemistry · Kinetics
First-order half-life is independent of initial concentration — don’t scale t½ with [A]₀.
Biology · Molecular Basis
Chargaff: A=T and G≡C. Given %A, %T equals it and %G+%C make the rest — don’t assume 25% each.
Biology · Human Physiology
Arteries carry blood AWAY from the heart (mostly oxygenated) — except the pulmonary artery. Don’t over-generalise.
