Abstract
The utility model discloses a momentum conservation demonstration instrument. The momentum conservation demonstration instrument comprises a base, a first semicircular slot, a second semicircular slot, a supporting post, a ball falling pool and metal balls, wherein threaded holes are formed in the four corners of the base; bolts, which are adaptive to the threaded holes, are arranged on the four corners of the base; a first semicircular slot is embedded along the base; the ball falling pool is fixedly connected with the right end of the base; a second semicircular slot is fixedly and smoothly connected with the first semicircular slot; the left end of the second semicircular slot is fixedly connected with the upper surface of the base by the supporting post; the diameter of the metal ball is a bit smaller than the inner diameter of the first semicircular slot; and the distances from the shaft axis of the first semicircular slot to the front and rear side surfaces of the base are equal. The bolts are rotated for adjusting the base to the horizontal state; six metal balls, which are next to one another, are placed in the first semicircular slot; seven metal balls are placed at the left end of the second semicircular slot and then are loosened; the balls are fallen down, elastically collided with the metal balls at the left end in the first semicircular slots and stopped; and finally, the metal balls at the inner rightmost end of the first semicircular slot are popped out, fallen to the ball falling pool, and the rest metal balls are still. The momentum conservation demonstration instrument has the beneficial effects that the instrument is simple, convenient and practical, and remarkable in experimental effect.
Description
Technical field
The utility model belongs to the physical experiment apparatus field, relates to a kind of momentum conservation demonstrator.
Background technology
The elastic collision billiards demonstration commonly used of existing momentum conservation is namely played 7 by the identical iron ball of arranging in a line under in the middle of two contour and parallel supports, each iron ball is separately fixed at two oblique lines on support by two and hauls.During demonstration, hold an iron ball on limit, strain two ropes of this ball connected, this ball is raised to certain altitude looses one's grip, the iron ball collision that this ball is adjacent when moving to minimum point comes an iron ball on line and collides successively, and is last, only have an iron ball of another side to be ejected, other balls are static.This experiment effect is obvious, and the student likes.But often occur that rope is broken or two oblique ropes are not isometric, cause the iron ball centre of sphere, experiment can't not carried out point-blank.
Summary of the invention
In order to solve the problem of existence, the purpose of this utility model is to provide a kind of momentum conservation demonstrator, makes seven Metal Ball when collision, and the Metal Ball centre of sphere can be positioned on straight line all the time.
the technical scheme that its technical matters that solves the utility model adopts is: momentum conservation demonstrator, comprise base, the first half slot, the second half slot, pillar, falling sphere pond and Metal Ball, it is characterized in that: described base is rectangular parallelepiped, four jiaos are provided with threaded hole and the screw adaptive with threaded hole are installed, be inlaid with the first half slot along the base length direction, the first half slot right-hand member is concordant with the base right-hand member, the base right-hand member is fixedly connected with the falling sphere pond, fixed light slip between described the second half slot right-hand member and the first half slot left end, the second half slot left end is fixedly connected with by pillar with base upper surface, the diameter of described Metal Ball is slightly smaller than the internal diameter of the first half slot, the second half slot is all identical with the first half slot inner and outer diameter, the first half slot axial line equates to the distance of two sides, base front and back.
During use, rotate respectively four screws, transfer base to level, 6 Metal Ball are close to successively are placed in the first half slot, the centre of sphere of this ball will come on a line automatically, after being put into the second half slot left end, the 7th Metal Ball loose one's grip, this ball will roll down along the second half slot, in the first half slot with first Metal Ball generation elastic collision that has been placed on left end in this groove after static, only have at last the Metal Ball that has been placed on low order end in the first half slot to be ejected, fall in the falling sphere pond, all the other Metal Ball are all static.
The beneficial effects of the utility model are, simple and convenient practicality, experiment effect obviously, safety.

Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing:
as depicted in figs. 1 and 2, the utility model momentum conservation demonstrator, comprise base 1, the first half slot 5, the second half slot 6, pillar 7, falling sphere pond 3 and Metal Ball 21, it is characterized in that: described base 1 is rectangular parallelepiped, four jiaos are provided with threaded hole 2 and the screw 4 adaptive with threaded hole 2 are installed, be inlaid with the first half slot 5 along base 1 length direction, the first half slot 5 right-hand members are concordant with base 1 right-hand member, base 1 right-hand member is fixedly connected with falling sphere pond 3, fixed light slip between described the second half slot 6 right-hand members and the first half slot 5 left ends, the second half slot 6 left ends are fixedly connected with by pillar 7 with base 1 upper surface, the diameter of described Metal Ball 21 is slightly smaller than the internal diameter of the first half slot 5, the second half slot 6 is all identical with the first half slot 5 inner and outer diameter, the first half slot 5 axial lines equate to the distance of base 1 two sides, front and back.
During use, rotate respectively four screws 4, transfer base 1 to level, 6 Metal Ball 21 are close to successively are placed in the first half slot 5, the centre of sphere of these 6 balls will come on a line automatically, after being put into the second half slot 6 left ends, the 7th Metal Ball 21 loose one's grip, this ball will roll down along the second half slot 6, in the first half slot 5 be placed in this groove first Metal Ball 21 of left end and occured after elastic collisions static, only have at last the Metal Ball 21 that has been placed on the first half slot 5 interior low order ends to be ejected, fall in falling sphere pond 3, all the other Metal Ball 21 are all static.
