Abstract
The utility model provides an inertia instrument and belongs to a teaching model. The utility model mainly solves a problem of direct demonstration of inertial. The structure of the inertia instrument includes an inertia instrument body. The inertia instrument body is composed of a frame, a glass tube, a small ball, bolts and a pulley pedestal. The frame is in a hollow rectangular structure and two sides of the frame are provided with vertical through grooves respectively. The through grooves are provided with the bolts capable of adjusting heights. The horizontal glass tube is arranged in a hollow part of the frame. Two ends of the glass tube are arranged on the bolts. The small ball having the diameter smaller than the inner diameter of the glass tube is arranged in the tube. The frame is fixed on the pulley pedestal vertically. The upper surface of the pedestal is a flat board. Four corners of the bottom part of the flat board are provided with wheels. The inertia instrument provided by the utility model has a characteristic of simulating and demonstrating the existence of the inertia directly, thereby improving the understanding of the inertia.
Description
Technical field
The utility model relates to a kind of teaching mode, specifically a kind of inertia apparatus.
Background technology
In the teaching of physics lesson, when relating to Newton first law, used Galilean " gedanken experiment " method on the teaching material; Used equipment is more, does very trouble, and students also is not easy to understand; Make teaching efficiency very undesirable; Especially for the relatively poor school of condition, can't be equipped with corresponding experiment equipment, increase great difficulty to teaching.
The utility model content
The purpose of the utility model is to provide a kind of inertia apparatus, and this inertia apparatus has the function that simulation shows inertia exists.
The technical scheme that its technical matters of the utility model solution is taked is: a kind of inertia apparatus, and its structure comprises the inertia apparatus body, described inertia apparatus body is made up of framework, glass tube, bead, bolt and pulley base; Framework is hollow rectangular configuration, is respectively equipped with groove up and down in the framework both sides, and height-adjustable bolt is housed on the groove; Be provided with the glass tube of level at the framework hollow parts; The glass tube two ends are arranged on the bolt, and the bead of diameter less than the glass tube internal diameter is housed in the pipe, and framework is vertically fixed on the pulley base; Base upper surface is dull and stereotyped, and dull and stereotyped bottom is provided with wheel for four jiaos.
The beneficial effect of the utility model is: during experiment, utilize bolt that glass tube is adjusted to complete horizontal state, make bead be positioned at a left side (or right) end of glass tube; (or left side) level promotes base to the right; Also (or left side) rolling to the right in glass tube of bead this moment lets base stop suddenly then, and bead is not stop motion immediately but; But under inertia effect, continue to roll forward; Explain that with this object serves as under the situation of zero (being equivalent to not stress), with keeping original static or linear uniform motion state, promptly to meet Newton first law at suffered bonding force.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 framework, 2 glass tubes, 3 beads, 4 bolts, 5 pulley bases.
Embodiment
As shown in Figure 1.A kind of inertia apparatus, its structure comprises the inertia apparatus body, described inertia apparatus body is made up of framework 1, glass tube 2, bead 3, bolt 4 and pulley base 5; Framework 1 is hollow rectangular configuration, is respectively equipped with groove up and down in framework 1 both sides, and height-adjustable bolt 4 is housed on the groove; Be provided with the glass tube 2 of level at framework 1 hollow parts; Glass tube 2 two ends are arranged on the bolt 4, and the bead of diameter less than glass tube 2 internal diameters is housed in the pipe, and framework 1 is vertically fixed on the pulley base 5; Base upper surface is dull and stereotyped, and dull and stereotyped bottom is provided with wheel for four jiaos.
During experiment, utilize bolt 4 that glass tube 2 is adjusted to complete horizontal state, make bead 3 be positioned at a left side (or right) end of glass tube 2; (or left side) level promotes base 5 to the right; Also (or left side) rolling to the right in glass tube 2 of bead 3 this moment lets base 5 stop suddenly then, and bead 3 is not stop motion immediately but; But under inertia effect, continue to roll forward; Explain that with this object serves as under the situation of zero (being equivalent to not stress), with keeping original static or linear uniform motion state, promptly to meet Newton first law at suffered bonding force; It is scientific and interesting, simple in structure that the utility model integrates, and is easy to selection, making, especially is fit to school instruction and uses.
