Physics numericals in SEE Science account for approximately 18 marks. Every question draws from a finite set of foundational equations.
The 7 Indispensable Formulas
- $F = \frac{G m_1 m_2}{d^2}$ (Universal gravitation with distance doubling traps)
- $g = \frac{GM}{R^2}$ and acceleration due to gravity at altitude $g' = \frac{GM}{(R+h)^2}$
- Upthrust $U = v \cdot d \cdot g$ (Archimedes principle)
- Transformer turns ratio: $\frac{N_p}{N_s} = \frac{V_p}{V_s} = \frac{I_s}{I_p}$
- Electric power consumption: $\text{Units} = \frac{P (\text{Watts}) \times t (\text{Hours}) \times \text{Days}}{1000}$
- Wave speed equation: $v = f \cdot \lambda$
- Heat equation: $Q = m \cdot s \cdot dt$
