Physics and Mathematics is worth 13 marks (out of 90 total) on the IMAT. Historically, international medical candidates lose more points here than in any other section—not because the calculations are difficult, but because high school candidates skip thermodynamics, electromagnetism, and coordinate geometry during revision.
Under Ministerial Decree (DM) n. 1005, the IMAT tests 60 multiple-choice questions in 100 minutes. Gaining even 8 to 10 points in Physics & Maths frequently bridges the gap between getting waitlisted and securing a first-choice seat at Milan, Bologna, or Sapienza.
1. High-Yield Formula Reference (DM 1005 Syllabus)
🌡️ Thermodynamics & Heat
* **Calorimetry & Temperature Change**:
§ Q = m \cdot c \cdot \Delta T
* **Latent Heat & Phase Changes**:
§ Q = m \cdot L_f \quad (\text{Fusion}) \quad | \quad Q = m \cdot L_v \quad (\text{Vaporization})
* **First Law of Thermodynamics**:
§ \Delta U = Q - W
* **Heat Engine Thermal Efficiency**:
§ \eta = \frac{W}{Q_H} = \frac{Q_H - Q_C}{Q_H} = 1 - \frac{Q_C}{Q_H}
⚡ Electromagnetism & Circuits
* **Coulomb's Law**:
§ F = k \cdot \frac{|q_1 \cdot q_2|}{r^2} \quad (k = 8.99 \times 10^9 \text{ N}\cdot\text{m}^2/\text{C}^2)
* **Electric Field & Potential**:
§ E = \frac{F}{q} = \frac{V}{d}
* **Capacitance & Equivalent Circuit Rules**:
§ C = \frac{Q}{V} \quad | \quad C_{\text{series}} = \left(\frac{1}{C_1} + \frac{1}{C_2}\right)^{-1} \quad | \quad C_{\text{parallel}} = C_1 + C_2
* **Ohm's Law & Electrical Power**:
§ V = I \cdot R \quad | \quad P = V \cdot I = I^2 \cdot R = \frac{V^2}{R}
* **Kirchhoff's Junction Rule**:
§ \sum I_{\text{in}} = \sum I_{\text{out}}
* **Magnetic Force on a Moving Charge**:
§ F = q \cdot v \cdot B \cdot \sin(\theta)
* **Faraday's Law of Electromagnetic Induction**:
§ \text{EMF} = -\frac{\Delta \Phi_B}{\Delta t}
🚀 Mechanics & Energy
* **Centripetal Acceleration & Force**:
§ a_c = \frac{v^2}{r} = \omega^2 \cdot r \quad | \quad F_c = m \cdot \frac{v^2}{r}
* **Period of Mass-Spring Simple Harmonic Motion**:
§ T = 2\pi \sqrt{\frac{m}{k}}
* **Impulse & Momentum Theorem**:
§ J = \Delta p = F \cdot \Delta t = m(v - u)
* **Conservation of Mechanical Energy**:
§ E_{\text{total}} = E_k + E_p = \frac{1}{2} m v^2 + m g h = \text{constant}
📐 Mathematics, Functions & Coordinate Geometry
* **Distance Between Two Points**:
§ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
* **Perpendicular Lines Slope Condition**:
§ m_1 \cdot m_2 = -1 \implies m_2 = -\frac{1}{m_1}
* **Standard Circle & Parabola Equations**:
§ (x - h)^2 + (y - k)^2 = r^2 \quad | \quad x_{\text{vertex}} = -\frac{b}{2a}
* **Trigonometric Radians & Identity**:
§ \theta (\text{rad}) = \text{deg} \cdot \frac{\pi}{180^\circ} \quad | \quad \sin^2(\theta) + \cos^2(\theta) = 1
2. Psychological & Test-Taking Mindset Tactics
🧠 The +1.5 / 0 / -0.40 Scoring Math
* **Correct**: $+1.5$ points
* **Unanswered**: $0$ points
* **Incorrect**: $-0.40$ points
The Rule: Never make a wild 1-in-5 guess (expected value $= \frac{1.5}{5} - \frac{4 \times 0.4}{5} = +0.30 - 0.32 = -0.02$). However, if you can eliminate even one wrong distractor, the expected value turns positive:
* Eliminating 1 option $ o$ expected value $= +0.075$
* Eliminating 2 options $ o$ expected value $= +0.233$
* Eliminating 3 options $ o$ expected value $= +0.550$
⏱️ The Two-Pass Strategy for 100 Minutes
1. **Pass 1 (0 to 60 min)**: Solve all Biology, Chemistry, Reading, and short conceptual Physics/Math questions first. Put a star next to calculation-heavy questions.
2. **Pass 2 (60 to 95 min)**: Execute full calculations for Physics & Maths. Because you already locked in 40+ points in Pass 1, your stress hormones (cortisol) decrease, preventing arithmetic slips.
3. **Pass 3 (95 to 100 min)**: Verify bubble sheet entries and ensure zero mis-aligned answers.
