a = v / t
F = ma
p = F⊥ / A
W = Fd
W = mgh
KE = (1/2)mv²
PE = mgh
PE = (1/2)Ky²
PE = (1/2)(V/P₀)p²
PE = (2T / L)y²
Ƥ = W / t

PE = (1/2)Ky²
ƒ = -Ky
ƒ = (1/2π)√(g/l)
ƒ = (1/2π)√(ΥpA/ml)
ƒ = (v/2π)√(a/Vl)
m = ρal
K = ρa²v² / V
V = (4/3)πr³

//===============
//Chapter 3:
//===============
v = ƒλ
v = √(E/ρ)
v = √(T/μ)
v = √(ΥRT/M)
ƒ'= ƒs ((v+v₀)/v)
