Daraghmeh and Abdelhalim M. Ziqan Deparmen of Mahemaics and Saisics Arab American niversiy Jenin, Jenin, Palesine opyrigh Iyad A. Suwan, Mehqal G. Daraghmeh and Abdelhalim M. Ziqan. his is an open access aricle disribued under he reaive ommons Aribuion License, which permis unresriced use, disribuion, and reproducion in any medium, provided he original work is properly cied. Absrac In his paper, he general Frene-Serre sysem of circular moion body wih consan velociy is analyically solved in hree dimensional space. he angen, normal, and binormal vecors are found by reducing he sysem ino a high order ordinary differenial equaion. Solving his equaion gives a closed form of hose vecors. A special case of four dimensional Frene-Serre sysem is also solved in his work. Keywords: Frene-Serre, high order ODE, angen, Normal, Binormal, urvaure, orsion, circular orbis. Inroducion he Frene-Serre frame is one of he mos imporan ools ha analyze and describe he properies of a paricle along differeniable curves in Eucledian space [,].
2 744 Iyad A. Suwan, Mehqal G. Daraghmeh and Abdelhalim M. Ziqan Frene and Serre [] adaped he frame o curves by direcly expressing he changes in derivaives of he angen, normal and binormal vecors in erms of he frame. A few decades laer, afer he resul of Frene and Serre, heir heory was exended o surfaces [], also an n-dimensional vecor calculus formulaions of he sysem is developed [4]. Moreover, exensions o he frame have been proposed using quaernion-formulaions []. In applicaions, sudying he Frene- Serre sysems is of grea imporance in applied mahemaics, physics, engineering and many fields of science [ 5-9 ]. One of he mos imporan applicaions of he Frene-Serre frames is undersanding he kinemaic properies of circular bodies, like he circular orbis in black hole space [,]. In his case, undersanding he frame is useful in sudying he properies of hese orbis and provides inerpreaion of heir geomery. he general hree dimensional Frene-Serre sysem o be discussed in his paper is defined by: ( ( ( = ( ( ( ( here,, are he angen, normal and binormal vecor fields respecively, is he ime, =, =, and is he orsion. Sudying of sysems like ( has been carried ou in boh analyical and numerical approaches as in [-5]. his Sysem will be analyically solved in his paper for bodies of circular moion wih consan velociies.. Analysis and resuls. he hree Dimensional Sysem onsidering a circular moion body wih consan velociy leads o a consan curvaure and orsion, hence, differeniaing he hird equaion of ( wice and differeniaing he firs and he second equaions once wih respec o ime give = (

Solving i for makes he soluion of sysem ( obvious. onclusions and Fuure Perspecives In his paper, he Frene-Serre sysem ( is efficienly reduced o a homogeneous hird order ordinary differenial equaion which is solved for he binormal vecor field. he normal vecor field is obained by solving a linear sysem of firs order ordinary differenial equaions, while he angen vecor field can be found by solving a simple linear ordinary differenial equaion. A special case of four dimensional Frene-Serre sysem when he orsion is zero has been analyically solved. As a nex sep, a circular moion bodies wih non-consan velociies will be under consideraion.
