There is also a possibility that fragments can be ejected at escape velocity from Mars by asteroid impact…. it seems likely that at least some small very fraction of this material would ultimately collide with Earth. Eugene Merle Shoemaker

According to Bohr it was be expected that on further rise in. the velocity of the impacting electrons the other spectral lines would appear in succession at the excitation potentials calculated from the series diagram. Gustav Ludwig Hertz

Windmills, which are used in the great plains of Holland and North Germany to supply the want of falling water, afford another instance of the action of velocity. The sails are driven by air in motion - by wind. Hermann von Helmholtz
