2. Deep Dive: Core Topics & Concept Breakdown
2.1 Mechanics
- Kinematics: Displacement, velocity, acceleration; SUVAT equations for constant acceleration.
- Dynamics: Newton’s laws, free‑body diagrams, friction and circular motion.
- Work, Energy & Power: Work‑energy theorem, conservation of mechanical energy, power calculations.
Practice Problem
Problem: A car accelerates from rest to 20 m/s in 5 s. Calculate acceleration and distance covered.
Solution: a = (v–u)/t = 4 m/s²; s = ut + ½at² = 0 + ½×4×25 = 50 m.
2.2 Thermal Physics
- Temperature vs Heat: First law of thermodynamics; specific heat capacity.
- Gas Laws: Boyle’s, Charles’s, and the ideal gas equation.
- Heat Transfer: Conduction, convection, radiation modes and calculations.
Quick Note
Use Q=mcΔT for calorimetry and ensure consistent units (J, kg, °C).
2.3 Electricity & Magnetism
- Electrostatics: Coulomb’s law, electric field and potential.
- Current Electricity: Ohm’s law, series vs parallel circuits, Kirchhoff’s laws.
- Magnetism: Magnetic fields, force on moving charge, electromagnetic induction.
Circuit Analysis
- Equivalent Resistance: Simplify series and parallel networks first.
- Power Dissipation: P=IV = I²R = V²/R.
2.4 Waves & Optics
- Wave Properties: Wavelength, frequency, speed; relation v=λf.
- Sound Waves: Doppler effect; resonance in tubes.
- Optics: Reflection, refraction (Snell’s law), lens formula (1/f = 1/v + 1/u).
Worked Optics Problem
Problem: An object 10 cm from a convex lens with focal length 5 cm. Find image distance and magnification.
Solution: 1/v=1/f−1/u=1/5−1/10=1/10 → v=10 cm; m=v/u=10/10=1.
3. Exam Strategy Tips
3.1 Time Management
- Aim for ~1.2 minutes per question.
- Tackle purely theory questions first (e.g., definitions, law identifications), then move to calculations.
- Flag multi‑step problems to revisit if time permits.
3.2 Structured Problem‑Solving
- Identify: List known quantities and what’s asked.
- Select: Choose relevant principle (e.g., conservation laws, lens formula).
- Solve: Substitute values with proper units; show clear steps.
- Verify: Check dimension consistency and reasonableness of the result.
3.3 Eliminating Incorrect Choices
- Use order‑of‑magnitude checks: e.g., v cannot exceed realistic limits.
- In circuit questions, estimate current direction and relative bulb brightness.
3.4 Diagram & Data Questions
- Annotate diagrams immediately; use a ruler for straight lines.
- For graphs, note axis scales and intercepts carefully.
3.5 Stress and Focus Techniques
- Use the 5‑4‑3‑2‑1 grounding method before the exam: name 5 things you see, 4 you can touch, etc.
- Positive affirmations: “I’ve mastered these formulas.”
