## Main Question or Discussion Point

So the equation for work is W = F * s

F = m * a, so W = m * a * s

Transferring this to units of measurement gives us: J = kg * m * s

Or simplified: J = kg * m

Transferring back to units of quantity: W = m * v

How can that be correct? Obviously E

F = m * a, so W = m * a * s

Transferring this to units of measurement gives us: J = kg * m * s

^{-2}* mOr simplified: J = kg * m

^{2}* s^{-2}Transferring back to units of quantity: W = m * v

^{2}How can that be correct? Obviously E

_{kin}= 1/2 * m * v^{2}. Where did that 1/2 go? Or is W =/= E_{kin}? Am I making some other kind of mistake?
