What is the formula for frequency?

f = 1/T


Rotational
S = ? 
S = R(theta)


Vt = ?

R(omega)


At = ?

R(alpha)
alpha = At/R 

Ac = ?

V^2/R


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

Ki + Ui + Wi>f = Kf + Uf


SHM
x(t) = 
x(t) = Acos(wt) >
Xmax = A 

v(t) =

v(t) = Aw sin (wt) >
Vmax = Aw 

A(t) =

A(t) = Aw^2 cos (wt) > Amax = Aw^2


Gravitational
Fgrav = 
Fgrav = (GmM)/r


V^2 =

v^2 = GM/r


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 = 
Vf = VoAt


Vf^2 =

Vf^2 = Vo^2 + 2a(delta S)


Sf =

Sf = So + Vot + 1/2at^2


Energy
Kt 
Kt = 1/2mv^2


Kr

Kr = 1/2Iw^2


U = ?

U = mgh


Uspg

Uspg = 1/2K(delta S)^2


Rotational
Wf = 
Wf = Wo + alpha(t)


Wf^2 =

Wf^2 = Wo^2 + 2(alpha)(delta theta)


Theta f

Theta o + Wot + 1/2(alpha)t^2
