Mechanics

v = u + at
s = ut + ½at²
v² = u² + 2as
s = ½(u + v)t

F = ma
W = mg
F = kx (Hooke's law)
p = mv (momentum)

KE = ½mv²
PE = mgh
Work = Fd cos θ
Power = W/t = Fv

Waves

v = fλ
T = 1/f
v = √(T/μ) (string)
v = √(B/ρ) (fluid)

n₁ sin θ₁ = n₂ sin θ₂
1/f = 1/v + 1/u
M = -v/u (magnification)

Fields

F = GMm/r²
g = GM/r²
PE = -GMm/r

F = kQq/r²
E = F/q = kQ/r²
V = Ed (uniform field)
C = Q/V = ε₀A/d

F = BIL sin θ
F = Bqv sin θ
EMF = -N dΦ/dt (Faraday)
