I don't know whether that was aimed at me Danny, but I am well versed in Physics.
I undestand the concept of momentum and kinetic energy. But the one other factor in the damage that can be cause is force and this is squarely proportional to surface area. For the winglet to have done what many on here believe to have happened ie slice into the 737's wing probably up to the spar it would have had to be a collision square on or there or there abouts to maximise force, and hence penetrating power. The failure of the winglet would tend to suggest this wouldn't be the case. Let's not forget for all the damage a bizjet will do with its kinetic energy, the 737 will do the same with it's as well with more due to greater mass.
That is the head on straight and level scenario. I'm sure there is a lateral component to this, and as the previous diagrams have shown this will take either a climb or bank from one or both. If so, why such a maneouver ??
