I yield and stand corrected . . . Momentum and Kinetic Energy are not the same. I do apologize for the inaccuracy. I still believe that the term " Speed is all you need! (?) is not accutate though.

My physics book disappeared many years ago (around 39) and my math is as rusty as my logic. But I am studying a page that may support my ultimate conclusion on the values of momenta and kinetic energy.

The following website explains why Kinetic Energy gets my vote over Mpmentum. And it is kind of cute the way they describe it.
