Volta was the inventor of the [[voltaic pile]], the first [[battery (electricity)|electrical battery]]. In common usage, the word "battery" has come to include a single galvanic cell, but a battery properly consists of multiple cells.&lt;ref>[http://www.merriam-webster.com/dictionary/battery "battery" (def. 4b)], ''Merriam-Webster Online Dictionary'' (2008).

Use of the term by T.E. Stern (1928) was misquoted as "Newton's constant of gravitation" in ''Pure Science Reviewed for Profound and Unsophisticated Students'' (1930), in what is apparently the first use of that term. Use of "Newton's constant" (without specifying "gravitation" or "gravity") is more recent, as "Newton's constant" was also used for the [[heat transfer coefficient]] in [[Newton's law of cooling]], but has by now become quite common, e.g. Calmet et al, ''Quantum Black Holes'' (2013), p. 93; P. de Aquino, ''Beyond Standard Model Phenomenology at the LHC'' (2013), p. 3. The name "Cavendish gravitational constant", sometimes "Newton–Cavendish gravitational constant", appears to have been common in the 1970s to 1980s, especially in (translations from) Soviet-era Russian literature, e.g. Sagitov (1970 [1969]), ''Soviet Physics: Uspekhi'' 30 (1987), Issues 1–6, p. 342 [etc.]. "Cavendish constant" and "Cavendish gravitational constant" is also used in Charles W. Misner, Kip S. Thorne, John Archibald Wheeler, "Gravitation", (1973), 1126f. Colloquial use of "Big G", as opposed to "[[little g]]" for gravitational acceleration dates to the 1960s (R.W. Fairbridge, ''The encyclopedia of atmospheric sciences and astrogeology'', 1967, p. 436; note use of "Big G's" vs. "little g's" as early as the 1940s of the [[Einstein tensor]] ''G''&lt;sub>''μν''&lt;/sub> vs. the [[metric tensor]] ''g''&lt;sub>''μν''&lt;/sub>, ''Scientific, medical, and technical books published in the United States of America: a selected list of titles in print with annotations: supplement of books published 1945–1948'', Committee on American Scientific and Technical Bibliography National Research Council, 1950, p. 26).|name=|group=}} denoted by the letter {{math|''G''}}, is an [[empirical]] [[physical constant]] involved in the calculation of [[gravitational]] effects in [[Sir Isaac Newton]]'s [[Newton's law of universal gravitation|law of universal gravitation]] and in [[Albert Einstein]]'s [[general relativity|general theory of relativity]].}} {{term|term=[[Gravitational energy]]|content='''[[Gravitational energy]]'''}}{{defn|defn=Gravitational energy or ''gravitational potential energy'' is the [[potential energy]] a [[mass]]ive object has in relation to another massive object due to [[gravity]].
