## Newton’s equations of motion – revisited
Last week, I showed how one could derive 3 of Newton’s equations of motion. As a colleague of mine pointed out to me on FaceBook, the 3rd equation I showed can, in fact, be derived using algebra from the 1st and 2nd.

Group Presentation of Dihedral Group $D_4$
The group presentation of the dihedral group $D_4$ is given by:
$D_4 = \gen {a, b: a^4 = b^2 = e, a b = b a^{-1} }$
