[2] Let x 1 and x 2 be the vector positions of the two bodies, and m 1 and m 2 be their masses. The goal is to determine the trajectories x 1 (t) and x 2 (t) for all times t, given the initial positions x 1 (t = 0) and x 2 (t = 0) and the initial velocities v 1 (t = 0) and v 2 (t = 0). When applied to the two masses, Newton's second law states that
If k 2 is greater than one, F 2 − F 1 is a negative number; thus, the added inverse-cube force is attractive, as observed in the green planet of Figures 1–4 and 9. By contrast, if k 2 is less than one, F 2 − F 1 is a positive number; the added inverse-cube force is repulsive , as observed in the green planet of Figures 5 and 10, and in ...
r = r 2 − r 1 is the vector position of m 2 relative to m 1; α is the Eulerian acceleration d 2 r / dt 2 ; η = G(m 1 + m 2). The equation α + η / r 3 r = 0 is the fundamental differential equation for the two-body problem Bernoulli solved in 1734. Notice for this approach forces have to be determined first, then the ...
TheSpark.com was a literary website launched by four Harvard students on January 7, 1999. Most of TheSpark's users were high school and college students. To increase the site's popularity, the creators published the first six literature study guides (called "SparkNotes") on April 7, 1999. [1] [3] [4] In 2000, the creators sold the site to iTurf ...
In (1+1) dimensions, i.e. a space made of one spatial dimension and one time dimension, the metric for two bodies of equal masses can be solved analytically in terms of the Lambert W function. [11] However, the gravitational energy between the two bodies is exchanged via dilatons rather than gravitons which require three-space in which to ...
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 ...
and are the masses of objects 1 and 2, and is the specific angular momentum of object 2 with respect to object 1. The parameter θ {\displaystyle \theta } is known as the true anomaly , p {\displaystyle p} is the semi-latus rectum , while e {\displaystyle e} is the orbital eccentricity , all obtainable from the various forms of the six ...
