## Homework Statement

The question is simply: Find a relation (one relation) between all of those (Work, Force, Moment, kinetic energy, linear momentum, impulse, angular momentum)

the question is like an impossible one !

thnx all

## Homework Equations

U:work T:kinetic energy F:force M:moment Imp:impulse Q:linear momentum H:angular momentum ω:angular velocity θ:angle

U

_{1->2}= T

_{2}-T

_{1}

T = (1/2)mv

^{2}+ (1/2)Iω

^{2}

U

_{1->2}= ʃ Fdr

rotation motion. U1->2 = Mdθ
