WebJan 6, 1998 · Abstract. We review the current status of our knowledge of cosmic velocity fields, on both small and large scales. A new statistic is described that characterizes the incoherent, thermal component of the velocity field on scales less than 2 h−1 Mpc ( h is H0 /100 km·s −1 ·Mpc −1, where H0 is the Hubble constant and 1 Mpc = 3.09 × 10 22 ...

Escape velocity - Wikipedia
With escape velocity in a direction pointing away from the ground of a massive body, the object will move away from the body, slowing forever and approaching, but never reaching, zero speed. Once escape velocity is achieved, no further impulse need be applied for it to continue in its escape. See more In celestial mechanics, escape velocity or escape speed is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a primary body, thus reaching an infinite distance from it. It … See more From the surface of a body An alternative expression for the escape velocity $${\displaystyle v_{e}}$$ particularly useful at the surface on the body is: $${\displaystyle v_{e}={\sqrt {2gr\,}}}$$ where r is the See more In this table, the left-hand half gives the escape velocity from the visible surface (which may be gaseous as with Jupiter for example), relative … See more • Black hole – an object with an escape velocity greater than the speed of light • Characteristic energy (C3) • Delta-v budget – speed needed to perform maneuvers. • Gravitational slingshot – a technique for changing trajectory See more The existence of escape velocity is a consequence of conservation of energy and an energy field of finite depth. For an object with a given total energy, which is moving subject to conservative forces (such as a static gravity field) it is only possible for the object to … See more If an object attains exactly escape velocity, but is not directed straight away from the planet, then it will follow a curved path or trajectory. Although this trajectory does not form a closed … See more Let G be the gravitational constant and let M be the mass of the earth (or other gravitating body) and m be the mass of the escaping body or projectile. At a distance r from the centre of … See more WebMar 2, 2024 · This is because all galaxies have some additional residual motion in addition to the pure expansion. This is referred to as the "cosmic velocity dispersion" or "cosmic scatter" and is probably due to the fact that the gas clouds that formed the galaxies all had some small additional motion of their own.
