Newtonian traffic safetyI've been exploring for oil and gas for so long now (and reading OGJ for just as long) that my college physics courses are pretty much forgotten. However, you are familiar with Einstein's E=mc2 which is related to the Newtonian K=1/2mv2. That is to say the kinetic energy K of a moving body is proportional to its mass but also to the square of its velocity. The big problem in a collision (Journally Speaking, Jan. 5, 2004, p. 15) is not the momentum (the product of mass x velocity) of the colliding bodies but the energy transfer.The modifier that prevents an SUV from being as devasting to a small car as it is to another SUV is the efficiency of energy transfe...
