Possibly useful equations for the Excursions OnLine midterm or final exam:
v = x/t

p = m v

a = v/t

PE = m g h

v = v_{i} + a t

PE = (^{1}/_{2}) k x^{2 }

x = x_{i} + v_{i} t + (^{1}/_{2})
a t^{2 }

KE = (^{1}/_{2}) m v^{2}

v = r

F = – k x

F = m a

E_{i} = E_{f}

F_{12} =  F_{21}

p_{i} = p_{f}

w = mg

F = ^{p}/_{t}

g = 9.8 m/s^{2}
10 m/s^{2}

T = 2

v = (wavelength) x (frequency) 
T = 2

L = (n) x (half wavelength) 
v =

c = 3.00 x 10^{8} m/s 
F = – k x

n = v / c 
f_{b} =  f_{1}  f_{2} 

^{1}/_{f} = ^{1}/d_{i} + ^{1}/d_{o} 
v = (freq) x (wavelength)

d_{i} = [^{1}/_{n}] d_{o} 
L = [n] x [^{wavelength}/_{2}]

M = – d_{i}/d_{o} 
M = ^{25 cm}/_{f}  
M = f_{obj} / f_{eye}
