Energy
Under standard assumptions, specific orbital energy of a hyperbolic trajectory is greater than zero and the orbital energy conservation equation for this kind of trajectory takes form:
where:
- is orbital velocity of orbiting body,
- is radial distance of orbiting body from central body,
- is the negative semi-major axis,
- is standard gravitational parameter.

Famous quotes containing the word energy:
“The persons who constitute the natural aristocracy, are not found in the actual aristocracy, or, only on its edge; as the chemical energy of the spectrum is found to be greatest just outside of the spectrum.”
—Ralph Waldo Emerson (1803–1882)
“I say, stamping the words with emphasis,
Drink from here energy and only energy,”
—Stephen Spender (1909–1995)
“Crime is naught but misdirected energy. So long as every institution of today, economic, political, social, and moral, conspires to misdirect human energy into wrong channels; so long as most people are out of place doing the things they hate to do, living a life they loathe to live, crime will be inevitable.”
—Emma Goldman (1869–1940)
