Mechanics
v = u + at → uniform acceleration
s = ut + ½at²
v² = u² + 2as
g = 9.81 m s⁻² (near Earth's surface)
Newton's 2nd Law: F = ma
Momentum: p = mv (conserved in closed system)
Impulse = FΔt = Δp
Waves & Optics
v = fλ v = wave speed, f = frequency, λ = wavelength
Speed of light: c = 3.0 × 10⁸ m s⁻¹
Snell's Law: n₁ sin θ₁ = n₂ sin θ₂
