Abstract
The utility model provides an elasticity demonstration device for physics teaching, which comprises a base, a spring, two guide rails, an iron ball and a white board with scales. The two guide rails are fixed on the base in parallel vertically, the white board with scales is vertically fixed on the base, the distance between the two guide rails and the white board can enable the iron ball to be clamped and move vertically in the two guide rails without being separated from the guide rails, the spring is installed at the central position of an area formed between the two guide rails and the white board, the iron ball is placed on the spring, and a layer of carbon paper is bonded to the white board. The elasticity demonstration device is simple in structure and clear and intuitive in display, thereby enabling students to grasp deeper perceptual knowledge and achieving the aims of class teaching.
Description
Technical field
The utility model relates to a kind of physics teaching apparatus, is specifically related to a kind of physics teaching and uses the elastic force apparatus for demonstrating.
Background technology
Shape or stereomutation that object takes place under the effect of power are called deformation.After external force fails, can restorable deformation be called elastic deformation.Elastically-deformable object takes place, the effect that can produce power to the object with its contact and the recovery deformation that holds it back.This power is elastic force, that is, within the elastic limit scope, object to the power of the application of force deposits yields that makes object generation deformation elastic force.Teacher is abstract explanation in the prior art, and the student accepts difficulty, and teaching efficiency is poor.
The utility model content
For overcoming the weak point of prior art, the utility model discloses a kind of physics teaching and uses the elastic force apparatus for demonstrating.When this device can intuitively show spring generation elastic deformation, the big or small F of elastic force was directly proportional with the length x of spring elongation (or shortening), i.e. F=-kx (or △ F=-k △ x).
The technical scheme that the utility model adopted is: a kind of physics teaching is used the elastic force apparatus for demonstrating; Comprise base, spring, two guide rails, iron balls and have the blank of scale; Article two, the guide rail parallel vertical is fixed on the base, and the blank that has scale also vertically is fixed on the base, and the distance of two guide rails and blank can be blocked iron ball; Iron ball is moved up and down and getaway not in two guide rails; Spring is installed in the regional center position that forms between two guide rails and the blank, and iron ball is placed on the spring, is stained with one deck transfer paper on the blank.
The utility model is simple in structure, show clear, directly perceived, thereby make the student produce darker perceptual knowledge, reach the classroom instruction purpose.
Description of drawings
Fig. 1 is the structural representation of the utility model, wherein 1, base, and 2, guide rail, 3, iron ball, 4, spring, 5, blank, 6, transfer paper, 7, scale mark.
Embodiment
Further specify according to Figure of description: a kind of physics teaching is used the elastic force apparatus for demonstrating; Comprise base, spring, two guide rails, iron balls and have the blank of scale; Article two, the guide rail parallel vertical is fixed on the base, and the blank that has scale also vertically is fixed on the base, and the distance of two guide rails and blank can be blocked iron ball; Iron ball is moved up and down and getaway not in two guide rails; Spring is installed in the regional center position that forms between two guide rails and the blank, and iron ball is placed on the spring, is stained with one deck transfer paper on the blank.Pin iron ball during teaching, make length of spring compressed, the iron ball of opening, spring are replied deformation, the iron ball of upspringing, and iron ball marks the marking along the guide rail certain altitude that rises on transfer paper, be imprinted onto on the blank, thereby have scale mark to calculate the height that iron ball rises on the blank.Revision test once more, compression spring is different length, last record data.Arrive thus when intuitively showing spring generation elastic deformation, the big or small F of elastic force is directly proportional with the length x of spring elongation (or shortening), i.e. the purpose of F=-kx (or △ F=-k △ x).
