The so-called periodicity refers to the fact that after a certain period of time, the moving object repeats back to its original position, and the instantaneous speed repeats back to its original size and direction. The time it takes for an object to move in a uniform circle is called a period. The period is expressed by the symbol T, and the period is also a physical quantity describing the speed of uniform circular motion.

I remember he first shot with his backhand and knocked out the one closest to him, and then he wanted to save people. Besides the company commander, there was also a platoon officer on our side. The platoon officer shouted to death with a broken gong voice, shouting only two words, "come back!" , probably out of instinct plus the role of command, he hesitated for a moment and turned to run back, and he ran back, is to pick up a life, but the other three comrades, born by those things to tear, some bit off the throat, some was torn off the arm沛公刘邦西进关中，出发已有数月时间。　　林禾担心家庭和爱情受到伤害，一改往日的宽容善良，果断地迫使袁牧野搬家与沙小修决断。岂
