The runge-lenz vector
Did you know?
WebbThis problem is known to be super-integrable and in two dimensions, and the set of its three integrals of motion makes up the components of the so-called Runge–Lenz vector . Here, we adopt the notations of [ 12 ], with the particle mass set equal to one. It is also known as the Laplace vector, the Runge–Lenz vector and the Lenz vector. Ironically, none of those scientists discovered it. The LRL vector has been re-discovered and re-formulated several times; for example, it is equivalent to the dimensionless eccentricity vector of celestial mechanics. Visa mer In classical mechanics, the Laplace–Runge–Lenz (LRL) vector is a vector used chiefly to describe the shape and orientation of the orbit of one astronomical body around another, such as a Visa mer An inverse-square central force acting on a single particle is described by the equation The corresponding Visa mer The conservation of the LRL vector A and angular momentum vector L is useful in showing that the momentum vector p moves on a circle under an inverse-square central force. Visa mer A single particle moving under any conservative central force has at least four constants of motion: the total energy E and the three Cartesian components of the angular momentum vector L with respect to the center of force. The particle's orbit is confined to the … Visa mer The LRL vector A is a constant of motion of the Kepler problem, and is useful in describing astronomical orbits, such as the motion of planets … Visa mer The shape and orientation of the orbits can be determined from the LRL vector as follows. Taking the dot product of A with the position vector r … Visa mer The seven scalar quantities E, A and L (being vectors, the latter two contribute three conserved quantities each) are related by two equations, A ⋅ L = 0 and A = m k + 2 mEL , giving … Visa mer
