This pa.er focuses on Ga.ss principle of lea.t compulsion for rela.ive motion dyna.ics a.d derives differentia. equa.ions of motion from it. Firstly, sta.ting from the dyna.ic equa.ion of the rela.ive motion of pa.ticles, we give the Ga.ss principle of rela.ive motion dyna.ics. By constructing a.compulsion function of rela.ive motion, we prove tha. a. a.y insta.t, its rea. motion minimizes the compulsion function under Ga.ssia. va.ia.ion, compa.ed with the possible motions with the sa.e configura.ion a.d velocity but different a.celera.ions. Secondly, the formula.of a.celera.ion energy a.d the formula.of compulsion function for rela.ive motion a.e derived beca.se the ca.ried body is rigid a.d moving in a.pla.e. Thirdly, the Ga.ss principle we obta.ned is expressed a. a.pell, La.ra.ge, a.d Nielsen forms in genera.ized coordina.es. Utilizing Ga.ss principle, the dyna.ica. equa.ions of rela.ive motion a.e esta.lished. Fina.ly, two rela.ive motion exa.ples a.so verify the results' correctness.
