To master the AP EAPCET 2026 (formerly AP EAMCET) Physics section, you need to navigate 28-30 chapters across both years of the Intermediate curriculum. The exam features 40 questions, and since there is no negative marking, accuracy in high-weightage areas is your best strategy.
1. Mechanics (1st Year Foundation)
Mechanics usually accounts for 10–12 questions . It is the "heavy lifting" part of the syllabus.
- Units and Measurements: SI units, error analysis (significant figures), and dimensional formulas.
- Kinematics: Motion in a straight line and plane, Projectile Motion, and Relative Velocity.
- Laws of Motion: Newton’s laws, momentum, impulse, and Friction (including circular motion on banked roads).
- Work, Energy, and Power: Work-energy theorem, potential/kinetic energy, and Collisions (one and two dimensions).
- Systems of Particles & Rotational Motion: Center of mass, torque, angular momentum, and Moment of Inertia theorems.
- Gravitation: Kepler’s laws, variation of $g$ with height/depth, and satellite escape velocity.
2. Thermal Physics (1st Year)
This unit is compact but carries high marks (5–7 questions).
- Thermal Properties of Matter: Temperature, expansion, calorimetry, and Newton's law of cooling.
- Thermodynamics: Zeroth, First, and Second laws; Isothermal and Adiabatic processes; and the Carnot Engine.
- Kinetic Theory: Behavior of ideal gases and the law of equipartition of energy.
3. Electricity and Magnetism (2nd Year)
This is the most formula-heavy section and accounts for 10–12 questions.
- Electrostatics: Coulomb’s law, electric field, Gauss’s law, and Capacitors in series/parallel.
- Current Electricity: Ohm’s Law, Kirchhoff’s Laws, Wheatstone Bridge, and Potentiometer.
- Moving Charges & Magnetism: Biot-Savart Law, Ampere’s Law, Cyclotrons, and magnetic force on conductors.
- Magnetism and Matter: Earth's magnetism and properties of materials (Dia, Para, Ferro).
- EMI and Alternating Current: Faraday’s law, Lenz’s law, and LCR Circuits (Resonance and Power factor).
4. Optics and Waves (1st & 2nd Year)
A conceptual section contributing 5–7 questions.
- Oscillations (1st Year): Simple Harmonic Motion (SHM) and the simple pendulum.
- Waves (2nd Year): Speed of sound, Doppler Effect, and Beats.
- Ray Optics: Reflection/Refraction, Lenses, Prisms, and Optical Instruments.
- Wave Optics: Huygens' principle, Interference (Young’s Double Slit), and Diffraction.
5. Modern Physics & Electronics (2nd Year)
The "scoring zone"—questions here are often direct and less time-consuming (4–6 questions).
- Dual Nature of Matter: Photoelectric effect and de Broglie wavelength.
- Atoms & Nuclei: Bohr’s model, atomic spectra, Radioactivity, and Nuclear fission/fusion.
- Semiconductors: P-N Junction diodes, Rectifiers, and Logic Gates.
- Communication Systems: Signal modulation and bandwidth.
Pro Tip: Don't get stuck on difficult Rotational Mechanics problems early on. Secure your marks in Modern Physics and Heat first, as they are often purely formula-based.
