| description | The utility model relates to a projectile motion instantaneous speed determination of direction device, a horizontal installation scale on the base plate on track least significant end right side, a horizontal installation slide bar on the base plate of this scale top, two sliders of suit on this slide bar, the laser of vertical direction is throwed to striking point in the back vertical laser pointolite is used for removing to the striking point that forms on the blank sheet of paper when receiving plate resistance fender pombe directly over, when universal laser pointolite is used for removing probe distance's between vertical laser pointolite and the track least significant end mid point to striking point throws the laser of incline direction, and the laser of this incline direction does promptly striking point instantaneous speed's direction. The utility model discloses in, the student can obtain striking points different on the parabola to observe the instantaneous speed direction of every striking point |
