This lesson focuses on circular velocity and escape velocity. The lesson shows formulas, explanations, and examples related to these concepts.
The main difference between orbital and suborbital flight is the speed at which a vehicle is traveling. An orbital spacecraft must achieve what is known as orbital velocity, whereas a suborbital rocket flies at a speed below that. Orbital velocity is the speed that an object must maintain to ...
Orbital angular velocity refers to how fast a point object revolves about a fixed origin, i.e. the time rate of change of its angular position relative to the origin. Spin angular velocity is independent of the choice of origin, in contrast to orbital angular velocity which depends onthe cho...
require isolation from vehicle motions in the acquisition and terminal phases, in turn depends on the nature and accuracy of the vehicle stabilization and control systein, and the number and location of corrective rockets which will affect the reorientation requirements to achieve velocity corrections....
The fixation can remain locked on the target as long as the movement is smooth and the velocity below about 40°/s. Abnormal pursuit eye movements could be due to ocular motor nerve palsy, cerebellar disease, internuclear ophthalmoplegia, systemic medication, etc. Syn. following movement. See...
The stretching velocity was set as 5 mm/min, which is equivalent to the eyeball rotating with an angular velocity of 0.5 °/s. However, the angular velocity of both fixations and rapid eye movements can be up to 900 °/s [12]. The test was stopped when the tensile displacement reached...
on the Moon. Impacts on the Moon have typical impact speed of 22 km s−1and as high as 55 km s−126,27. Very small ejected debris particles may achieve comparable speeds, although the total fraction of such very high–velocity ejecta (solid or molten) is exceedingly small28,29. ...

By analogy with the typical energy of the electrons generating the auroral planetary radio emission in the Solar System (a few keV), this velocity is assumed to be v = 0.1 c in the present paper. The last step is to compare the directions of emission with the direction of the observer ...
velocity causing solid body rotation. The mixture possesses a two dimensional vector having a slight radially inward component as well as a strong downward directional component. Since horizontal frictionless flow occurs in the separation chamber, the isobars 92 should represent areas where acceleration ...
