presented the steps of a nonlinear mathematical procedure for obtaining, from elevation measurements in the field (and in the laboratory), the nonlinear orbital velocity
in directional seas, including the effect of a current;
By calculating a planet's orbital velocity
in a circular orbit, they could then estimate a transit's duration -- how long a planet would take to cross in front of a star.
The intense laser beam focused on the debris will produce high-velocity plasma ablation, and the reaction force will reduce its orbital velocity
, leading to its reentry into the earths atmosphere.
Physical meaning of critical energy is that the ion laboratory velocity is greater than the orbital velocity
of the electron in hydrogen atom.
The orbital velocity
of the Moon is approximately 1000 meters/sec.
To obtain the orbital velocity
necessary to reach its comet target, the Rosetta spacecraft took advantage of four gravity assists (three from Earth, one from Mars) and an almost three-year period of deep space hibernation, waking up in January 2014 in time to prepare for its rendezvous with 67P/Churyumov-Gerasimenko.
But by studying how the starlight shifted as it passed through the atmosphere of exoplanet HD 209458b (illustrated), Dutch researchers found the planet's orbital velocity
Earth is a great place to pick up orbital velocity
It is not sufficiently powerful to reach orbital velocity
on its own so has to be launched by a rocket.
keeps space objects from being pulled in by gravity from a larger body such as the Sun.
Highlights include file footage of Sergei Korolev, designer of the R-7 rocket that launched Sputnik, and a lucid illustration of Isaac Newton's concept of orbital velocity
The second and third stages separated successfully and the missile reached orbital velocity
, but the attempt failed because the third-stage booster malfunctioned.
