a spacecraft uses the orbital speed of a planet to increase its own speed and to change the direction of its flight at the same time. The effect is similar to bouncing a plastic ball off the front of a moving car. The ball changes direction and picks up speed from the car. 在一个重...

Both particle beams and lasers are line of sight, speed of light weapons. This could make for some mighty short wars! They are very similar in needing millions of kilowatts of power and large heat sinks (because they are not very efficient) and both work better in space. Either method, ...
Δi=Δv/vin the case Δv<<v. As the velocity increment Δvneeded to achieve a given inclination increment Δiis proportional to the spacecraft speed at the instant of the manoeuvre (firing of the rocket motor), this operation should be performed at theapoapsis(where the speedvis a ...
Answer and Explanation:1 There are seven f orbitals, six of which are formed of six 'lobes' each, centered at the nucleus, while the remaining orbital is composed of two lobes... Learn more about this topic: Electron Orbitals | Definition, Subshells & Shapes ...
speed at which it orbits around the barycenter of a system, usually around a more massive body. It can be used to refer to either the mean orbital speed, i.e. the average speed as it completes an orbit, or the speed at a particular point in its orbit 相关学科: ...
Tags Orbital Orbital period Period Planet In summary, the equation P2 = (4 * pi2 * a3)/(G(M+m)) can be used to find the orbital period of Earth, where P is the orbital period, a is the semi-major axis, G is the gravitational constant, M is the mass of the sun, and m is ...
The Moon has an orbit period of 27.3 days and an orbital radius of 3.84×108m. Find the orbital velocity of the moon in m/s. Circular Motion: The rate of change of angular position of a particle with respect to time is called angular speed. The relation between t...
of, relating to, or forming an orbit (such as the orbit of a moon, planet, or spacecraft) The Gregorian calendar is purely based on the position of the sun as seen from Earth, and is closely related to the Earth's orbital period.—Martin George In October 1957, a whirling orbital ba...
