Since the kinetic energy increases with the square of the speed, an object doubling its speed has four times as much kinetic energy. For example, a car traveling twice as fast as another requires four times as much distance to stop, assuming a constant braking force.
Google is your friend. :) Bally is an extremely common prefix to town names in Ireland, and is derived from the Gaelic phrase 'Baile na', meaning 'place of'. It is not quite right to translate it 'town of', as there were few, if any, towns in Ireland at the time these names were formed.
Most modern descendants of the Irish group go by the name of Curley. Older documentation of the family reveals a profuse range of variations on this family's name, including, but not limited to, English language spellings of Curley, Curly, Curoly, Kerly, Kerryle, Kirrily, Kirilie, Kirle, Kurylly, Kyrrell, and Kyrrelly.he Annals of Ulster record a MacOirghiallaigh in the year 1447 AD. There is substantial evidence that MacOirghiallaigh is the origin of the Curley name, so this individual may well be the progenitor of the Irish Curleys.
