WebDec 9, 2008 · To get a centrifugal force you must be working in a rotating frame, specifically a frame rotating with the Earth/Moon orbital angular velocity. The point with respect to which you wish to express the centrifugal force is the Earth-Moon barycenter, which is about 4670.3 km from the center of the Earth. http://www.earthmatrix.com/sciencetoday/moon/barycenter.html
Moon - Wikipedia
WebThe barycenter is typically located at a distance of about 5000 km from the center of the Earth, which is about 1300 km beneath the Earth's surface. Thus we may envision the translational inertial motion of the Earth as follows: Earth orbits the Earth—Moon barycenter, while this barycenter orbits the Sun, which in turn loops about the ... WebDec 2, 2024 · How can Earth-Centered Inertial (ECI) coordinates be inertial if Earth's orbital motion is always accelerating? a = d v d t ≈ − G M S u n r 2 has a magnitude of about 0.006 m/s^2 and always points roughly towards the Sun, so we are always falling towards the Sun. how to say goodnight to your boyfriend

WebFeb 11, 2024 · @DavidHammen's answer is of course spot-on correct, but I understand why you would have thought that this might be the right period. It is true that the Earth-Moon barycenter might move along a more representative Keplerian orbit than either the Moon or Earth alone, and if they were similar mass, this would be fairly obvious if you plotted their … WebThe Moon at perigee The Moon makes its monthly closest approach to the Earth, making it appear fractionally larger than at other times of the month.

WebIf we look at the Earth-Moon system as a two-body Keplerian system, we would expect Earth and the Moon to orbit their center of mass (barycenter) in perfect ellipses, with the barycenter at one of the foci of each body's ellipse, and with the bodies moving faster when closer to the barycenter and slower when farther from the barycenter. north harbour bays athletics club
