1. a kind of forst law of motion experimental technique, it is characterised in that includingTwo light electric switches, the respectively first smooth electric switch, the second smooth electric switch are chosen, and is connected with time set;

  • Choose light-weight metal ball bead;

    Transparent liquid medium is chosen, is loaded in slender glass cylinder;

    The larger transparent sewing machine oil of the described liquid medium selection coefficient of viscosity;

    Light-weight metal bead input is filled in the slender glass cylinder of sewing machine oil, under conditions of liquid is non-infinite broadness,The speed very little that bead falls in a liquid, wall is mutually supported to the squeezing action of liquid medium to the cross force that bead is producedDisappear, a upward resistance F is produced only in bead dropping process2, work as F2With viscosity resistance F1, gravity G and buoyancy F it is equalDuring weighing apparatus, i.e., bonding force sum is equal to zero suffered by bead, and then bead keeps speed during balance no longer to change, with even straight line speedFall.
