Hooke's Law states:
Stress is proportional to strain.
Frequency:
F = 1/T
W =
W = 2(pi)(f) = 2(pi)/T = square root of K/M
Uspg
Uspg = 1/2K(delta)s
Work Engergy Theorem

Kepler's Law:
GM/4pi^2 = r^3/T^2
g = (g = gravity on a planet)
g = GM/R^2
Circular Motion

S =
S = R(theta)
V =
V = R(omega)
A =
A = R(alpha)
Kinematics

Vf =

Kr = 1/2Iw^2
U = ?
U = mgh
Uspg
Uspg = 1/2K(delta S)^2
Rotational

Wf =
Wf = Wo + alpha(t)
Wf^2 =
