Definition of average velocity 
Vav = [delta]d/[delta]t 


Speed and angular velocity relationship 
[w thing] = v/r 


Definition of acceleration 
a = [delta]v/[delta]t 


Time of free fall 
t = sqrt(2y/g) 


Acceleration and angular acceleration relationship 
[curly a] = a/r 


Weight 
W = mg 
Its in Newtons 

Weight on an incline 
Fparallel = mgsin[theta] Fperpendicular = mgcos[theta] 
Force parallel AND force perpendicular 

Centripetal force 
Fc = mv^2/r 


Centripetal speed 
v = 2[pi]r/T 


Orbital speed 
v = sqrt(GM/r) 


Power 
P = Fv 


Workenergy theorem 
W = [delta]KE = (1/2)mvf^2  (1/2)mvi^2 


Conservation of energy 
KE0 + PE0 = FEf + PEf 


Conservation of energy (friction) 
KE0+PE0 = KEf+PEf+Energy (Ffd) 


Momentum and angular momentum 
L = pr 


Impulse (change in momentum) 
[delta]p = F[delta]t = m[delta]v 


Impulse (change in angular momentum) 
[delta]L = torquenet[delta]t = I[delta][curly w] 


Conservation of momentum (elastic) 
m1v1i + m2v2i = m1v1f +m2v2f 


Conservation of momentum (totally inelastic) 
m1v1i + m2v2i = (m1+m2)vf 


Conservation of momentum (recoil) 
(m1+m2)vi = m1v1f + m2v2f If vi=0: m1v1f = m2v2f 


Conservation of angular momentum 
(I1)f([curly w]1)f + (I2)f([curly w]2)f = (I1)i([curly w]1)i + (I2)i([curly w]2)i 


Harmonics string/open pipe 
fn = nv/2L 


Harmonics closed pipe 
fn = nv/4L 


Power relationships
