如图1所示,在转动的水平圆盘上,沿半径方向放着用细线相连的质量相等的两物体A和B,它们与盘间的摩擦因数相同且与圆盘保持相对静止.随着圆盘转动得越来越快,两物体所受的静摩擦力的大小和方向及细绳的张力大小均发生着微妙的变化,领悟这一变化,对认识静摩擦力、细绳的张力作为被动力,其大小随外界情 As shown in Fig. 1, on a rotating horizontal disk, two objects A and B of equal mass connected by a thin wire are placed in a radial direction with the same friction coefficient as that of the disk and relatively stationary with the disk. Disk rotation faster and faster, the two objects subject to the size and direction of the static friction and the tension of the rope have undergone a subtle changes in the understanding of this change, to understand the static friction, the tension rope as a passive , The size of the situation with the outside world
