In the late 17th century, Gottfried Leibniz proposed the idea of the Latin: vis viva, or living force, which defined as the product of the mass of an object and its velocity squared; he believed that total vis viva was conserved. To account for slowing due to friction, Leibniz theorized that thermal energy consisted of the random motion of the constituent parts of matter, a view shared by Isaac Newton, although it would be more than a century until this was generally accepted. The modern analog of this property, kinetic energy, differs from vis viva only by a factor of two.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is a term for living force?
Ah, so.. vis viva

From 1879, Watch Tower supporters gathered as autonomous congregations to study the Bible topically. Thirty congregations were founded, and during 1879 and 1880, Russell visited each to provide the format he recommended for conducting meetings. As congregations continued to form during Russell's ministry, they each remained self-administrative, functioning under the congregationalist style of church governance. In 1881, Zion's Watch Tower Tract Society was presided over by William Henry Conley, and in 1884, Charles Taze Russell incorporated the society as a non-profit business to distribute tracts and Bibles. By about 1900, Russell had organized thousands of part- and full-time colporteurs, and was appointing foreign missionaries and establishing branch offices. By the 1910s, Russell's organization maintained nearly a hundred "pilgrims," or traveling preachers. Russell engaged in significant global publishing efforts during his ministry, and by 1912, he was the most distributed Christian author in the United States.

Arsenal finished in either first or second place in the league in eight of Wenger's first eleven seasons at the club, although on no occasion were they able to retain the title. As of July 2013, they were one of only five teams, the others being Manchester United, Blackburn Rovers, Chelsea, and Manchester City, to have won the Premier League since its formation in 1992. Arsenal had never progressed beyond the quarter-finals of the Champions League until 2005–06; in that season they became the first club from London in the competition's fifty-year history to reach the final, in which they were beaten 2–1 by Barcelona. In July 2006, they moved into the Emirates Stadium, after 93 years at Highbury.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who did Arsenal compete against in the 2005-06 Championship League?
Ah, so..
unanswerable
