| Abstract: | Plusing the acceleration to be living in the material point kinetics is the problem constantly encountering.Adjusting ought to approximately to attend school not to point kinetics in clearly and definitely proposes only.The original is first of all propose to depict the approximately idea that plus the acceleration in the acceleration movement that the material point changes into.In immediate future acceleration adjust time the variance ratio.Then educes equally to plus the acceleration in immediate future plus the acceleration with instantaneous and plus the acceleration style showed.Afterwards expound to plus the acceleration to be living the application in the actual problem. |

| Keywords: | equally to plus the acceleration immediate future plus the acceleration plus the acceleration |
