WebThus, for example, in the flight of a supersonic aircraft at three times the speed of sound (about 1 km/sec), the stagnation temperature amounts to about 400°C, whereas in the reentry of a spacecraft into the earth’s atmosphere at the first cosmic velocity (8.1 km/sec), the stagnation temperature reaches 8000°C. The velocity corresponding to the circular orbit is sometimes called the first cosmic velocity, whereas in this context the escape velocity is referred to as the second cosmic velocity. [11] For a body in an elliptical orbit wishing to accelerate to an escape orbit the required speed will vary, and will be greatest at periapsis … 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 to the centre of the planet or moon … See more • Black hole – an object with an escape velocity greater than the speed of light • Characteristic energy (C3) 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 … 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 … 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.
