🚀 Mechanics
- v = u + at
- s = ut + ½at²
- v² = u² + 2as
- F = ma
- p = mv | J = FΔt
🔄 Rotation
- τ = r × F = Iα
- L = Iω
- KE(rot) = ½Iω²
- I = Σmr²
- ω = ω₀ + αt
⚡ Electrostatics
- F = kq₁q₂/r²
- E = kq/r²
- V = kq/r
- C = Q/V
- U = ½CV² = Q²/2C
🔋 Current Electricity
- V = IR (Ohm’s Law)
- P = VI = I²R = V²/R
- Rs = R₁+R₂+R₃
- 1/Rp = 1/R₁+1/R₂+1/R₃
- Q = It | E = Pt
🔭 Optics
- 1/f = 1/v − 1/u
- m = v/u = −v/u
- n = c/v = sin i/sin r
- P = 1/f (in metres)
- λ = d sinθ (diffraction)
☢️ Modern Physics
- E = hν = hc/λ
- KE(max) = hν − φ
- λ = h/mv (de Broglie)
- E = mc²
- t½ = 0.693/λ
