Relative motion analysis is one method used to analyze bodies undergoing general planar motion.

On occasion objects move within a medium that is moving with respect to an observer. For example, an airplane usually encounters a wind - air that is moving with respect to an observer on the ground below. As another example, a motorboat in a river is moving amidst a river current - water that is moving with respect to an observer on dry land. In such instances as this, the magnitude of the velocity of the moving object whether it be a plane or a motorboat with respect to the observer on land will not be the same as the speedometer reading of the vehicle.

## Relative Motion Analysis

Relative Velocity Problems On this page I put together a collection of relative velocity problems to help you understand relative velocity better. From the point of view of a passenger on the car, what is the velocity of the motorcycle? A pedestrian on the ground sees the ball hit the pavement and then bounce straight up. What was the velocity of the ball relative to the truck? See answer Problem 3 A duck swims at a constant speed from one side of a river to the other side in a time of 4 seconds.

In the dynamical model of relative motion with circular reference orbit, the equilibrium points are distributed on the circle where the leader spacecraft is located. Based on L-P approach, periodic motions are expanded as formal series of in-plane and out-of-plane amplitudes. According to the method of polynomial expansions, a pair of modal coordinates is chosen, and the remaining state variables are expressed as polynomial series about the modal coordinates. In order to check the validity of series solutions constructed, the practical convergence is evaluated. Considering the fact that relative motion model is a special case of restricted three-body problem, the periodic configurations constructed in the model of relative motion are taken as starting solutions to numerically identify the periodic orbits in restricted three-body problem by means of continuation technique with the mass of system as continuation parameter. Studying the relative motion among satellites is of significance for configuration design of formation flying, constellation, and distributed spacecraft systems, where the mode of working in cooperation with several probes is required in many space missions. In the relative motion problem, the commonly adopted model is the Hill-Clohessy-Wiltshire HCW equations [ 1 ], which are used to describe the relative motion of two point-mass bodies under the gravitational influence of a central body.

Motion does not happen in isolation. To explore this idea further, we first need to establish some terminology. To discuss relative motion in one or more dimensions, we first introduce the concept of reference frames. When we say an object has a certain velocity, we must state it has a velocity with respect to a given reference frame. In most examples we have examined so far, this reference frame has been Earth. We can expand our view of the motion of the person on the train and say Earth is spinning in its orbit around the Sun, in which case the motion becomes more complicated. In this case, the solar system is the reference frame.

## Analysis Of Relative Motion In General

Motion does not happen in isolation. To explore this idea further, we first need to establish some terminology. To discuss relative motion in one or more dimensions, we first introduce the concept of reference frame s. When we say an object has a certain velocity, we must state it has a velocity with respect to a given reference frame.

Агент Колиандер нажал несколько кнопок, и кадры стали сменяться быстрее. Люди на подиуме с нетерпением ждали, когда на экране появится их бывший сослуживец Энсей Танкадо. Ускоренное проигрывание видеозаписи придавало изображению некоторую комичность. Вот Танкадо вышел на открытое место и залюбовался открывшимся перед ним зрелищем.

Ей нужно было сосредоточиться на неотложных вещах, требующих срочного решения. - Я возьму на себя лабораторию систем безопасности, - сказал Стратмор.  - Всю статистику по работе ТРАНСТЕКСТА, все данные о мутациях.

- Танкадо оставил нам только один выход-признать существование ТРАНСТЕКСТА. Такая возможность. Последний шанс.

Возможно.  - Стратмор пожал плечами.  - Имея партнера в Америке, Танкадо мог разделить два ключа географически. Возможно, это хорошо продуманный ход.

Когда она оглянулась, Дэвид Беккер лежал на полу, прижимая ладони к лицу и корчась от нестерпимого жжения в глазах. ГЛАВА 71 Токуген Нуматака закурил уже четвертую сигару и принялся мерить шагами кабинет, потом схватил телефонную трубку и позвонил на коммутатор. - Есть какие-нибудь сведения о номере? - выпалил он, прежде чем телефонистка успела сказать алло.

Беккер понимал, что через несколько секунд его преследователь побежит назад и с верхних ступеней сразу же увидит вцепившиеся в карниз пальцы. Он зажмурился и начал подтягиваться, понимая, что только чудо спасет его от гибели. Пальцы совсем онемели. Беккер посмотрел вниз, на свои ноги. До апельсиновых деревьев не меньше ста метров.
