ACADEMIC EXCELLENCE MODULE
Academic Preparation (Physics, Math & English)
Key conceptual formulas and high-yield problem frameworks tested in Preliminary Academic tests (for Technical Cadet Course, CAE, GDP, Navy PN Cadet) and Deputy President rapid-fire interviews.
Core Physics Formulas & Principles
Kinematics v = u + at | s = ut + ½at² | v² = u² + 2as
Standard constant acceleration motion equations. Newton’s 2nd Law F = ma | F = dp/dt
Force equals mass times acceleration or rate of change of momentum. Work & Power W = F·d·cos(θ) | P = W/t = F·v
Work in Joules, Power in Watts. Optics & Refraction n = c/v | n₁ sin(θ₁) = n₂ sin(θ₂)
Snell’s Law of Refraction. Electric Current V = IR | P = VI = I²R = V²/R
Ohm’s Law & Electrical Power equations. Fast Mental Mathematics Shortcuts
Speed, Distance & Time
Speed = Distance / Time | km/h to m/s: multiply by 5/18
Downstream / Upstream
Boat Speed = (Down + Up) / 2 | Stream Speed = (Down - Up) / 2
Work & Time
If A takes x days and B takes y days: Combined time = (x · y) / (x + y)
Percentage Change
((New Value - Old Value) / Old Value) × 100%
