Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical concerning the motion of rockets, satellites, and other spacecraft. The motion of these objects is usually calculated from Newton's laws of motion and the law of universal gravitation .
In astrodynamics, the vis-viva equation is one of the equations that model the motion of orbiting bodies.It is the direct result of the principle of conservation of mechanical energy which applies when the only force acting on an object is its own weight which is the gravitational force determined by the product of the mass of the object and the strength of the surrounding gravitational field.
Astrodynamics is the term used to describe the application of Newtonian mechanics to human-made objects in space, such as rockets and spacecraft. It is a subfield of celestial mechanics and ballistics .
Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets, satellites, and other spacecraft. The motion of these objects is usually calculated from Newton's laws of motion and the law of universal gravitation.
Orbital elements are the parameters required to uniquely identify a specific orbit.In celestial mechanics these elements are considered in two-body systems using a Kepler orbit.
The mathematical statement of the three-body problem can be given in terms of the Newtonian equations of motion for vector positions = (,,) of three gravitationally interacting bodies with masses :
In astrodynamics, an orbit equation defines the path of orbiting body around central body relative to , without specifying position as a function of time.Under standard assumptions, a body moving under the influence of a force, directed to a central body, with a magnitude inversely proportional to the square of the distance (such as gravity), has an orbit that is a conic section (i.e. circular ...
In astrodynamics the argument of periapsis ω can be calculated as follows: = | | | | If e z < 0 then ω → 2 π − ω.. where: n is a vector pointing towards the ascending node (i.e. the z-component of n is zero),
