Omega for simple pendulum
sqrt(g/l)
Omega for springs
sqrt(k/m)
Omega for physical pendulum
sqrt(mgh/I)
Frequency from omega
f = (1/2pi)w
Period from omega
T = (2pi)(1/w)
Max velocity of oscillation
v_max = Aw
Velocity at any point of oscillation
v = (w)(sqrt(A^2 - x^2))
Max acceleration of oscillation
a_max = A(w^2)
Acceleration at any point of oscilation
a = -x(w^2)
