Description

Technical Field

[0001] This utility model belongs to the technical field of physics demonstration teaching aids, and is particularly related to a gravitational potential energy experimental demonstrator. Background Technology

[0002] In traditional physics teaching, demonstration experiments on gravitational potential energy typically consist of a base, a metal ball, a sponge plate, and a striking pin. Existing demonstrators release the steel ball manually, leading to significant errors in the ball's height, and requiring multiple sets of comparative experiments to be conducted simultaneously. Furthermore, these demonstrators use the depth of the striking pin's penetration into the sponge plate to determine the magnitude of the ball's gravitational potential energy; once the sponge plate is punctured, it cannot fully recover, affecting the accuracy of subsequent experiments. These demonstrators fail to comprehensively demonstrate the factors influencing gravitational potential energy, thus preventing students from intuitively understanding and mastering these factors. Utility Model Content

[0003] In view of the problems existing in the above-mentioned background technology, this utility model proposes a gravitational potential energy experimental demonstrator, which can control the fall of a steel ball through an electromagnet release device, can intuitively display the magnitude of gravitational potential energy, and can also conduct repeated experiments.

[0004] Therefore, this utility model adopts the following technical solution: a gravitational potential energy experiment demonstrator, including a frame, a reference demonstration group, at least one equal-height comparison demonstration group at the same height as the reference demonstration group, and at least one unequal-height comparison demonstration group at a different height from the reference demonstration group. Each of the reference demonstration group, equal-height comparison demonstration group, and unequal-height comparison demonstration group includes an electromagnet assembly for attracting a falling demonstration steel ball and a ball-receiving box for catching the falling demonstration steel ball. The ball-receiving box is magnetically attached to a guide block. The ball-receiving box is initially positioned at the same height and uniformly adjusted to the zero-scale position, and a scale is provided. The electromagnet assemblies of the reference demonstration group and the equal-height comparison demonstration group are at the same height, while those of the reference group and the unequal-height comparison group are at different heights. The demonstrator is placed horizontally on a table. Power is turned on to control the electromagnet assembly. The attraction switch is toggled to attract the steel ball to the electromagnet assembly. Steel balls of different masses are attracted to the electromagnet assemblies at the same height. The attraction switch is toggled to the release position to release the steel ball, allowing it to fall freely. A steel ball strikes a receiving box below. By comparing the displacement of the receiving box during its fall, the gravitational potential energy of balls of different masses at the same height is compared. Steel balls of equal mass are attracted to electromagnet components at unequal heights. Flipping the attracting switch to the release position releases the steel balls, allowing them to fall freely. The steel ball strikes the receiving box below, and by comparing the displacement of the receiving box during its fall, the gravitational potential energy of balls of the same mass at different heights is compared.

[0005] The frame includes a base and a demonstration panel. The demonstration panel is fixed to the base. The two sides of the demonstration panel are fixed by vertical bars, and the top of the demonstration panel is fixed by a horizontal bar. The horizontal bars and vertical bars are connected by arc-shaped corner fittings. The two sides of the base are fixed by base end caps to improve the stability of the frame demonstration.

[0006] This invention achieves the following beneficial effects: The gravitational potential energy experimental demonstrator uses an electromagnet to control the release of a steel ball, effectively reducing experimental errors. The demonstrator reflects the magnitude of gravitational potential energy by measuring the height of the falling magnetic ball-receiving box; it allows for repeated experiments with no consumable loss and high precision. This invention can be used to demonstrate the relationship between the magnitude of gravitational potential energy and mass, and the relationship between the magnitude of gravitational potential energy and height.

[0011] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. The described embodiments are only for illustration and explanation of this utility model and do not constitute the only limitation of this utility model.

[0012] like Figures 1-4 As shown, this utility model includes a frame 1, a reference demonstration group 2, two equal-height comparison demonstration groups 3 at the same height as the reference demonstration group, and two unequal-height comparison demonstration groups 4 at different heights from the reference demonstration group. Reference demonstration group 2, equal-height comparison demonstration group 3, and unequal-height comparison demonstration group 4 all include an electromagnet assembly 6 for attracting the falling demonstration steel ball 5 and a ball-receiving box 7 for catching the falling demonstration steel ball 5. The ball-receiving box 7 is magnetically attached to a guide block 8. The ball-receiving box 7 is initially positioned at the same height and uniformly adjusted to the zero-scale position, and a scale is provided. The electromagnet assemblies of reference demonstration group 2 and equal-height comparison demonstration group 3 are at the same height, while the electromagnet assemblies of reference demonstration group 2 and unequal-height comparison group 4 are at different heights.

[0013] As a preferred embodiment of the demonstrator, the frame 1 includes a base 15 and a demonstration panel 11. The demonstration panel 11 is fixed on the base 15. The two sides of the demonstration panel 11 are fixed by vertical rods 12, and the top of the demonstration panel 11 is fixed by a horizontal rod 13. The horizontal rod 13 and the vertical rod 12 are connected by an arc-shaped connecting corner piece 14. The two sides of the base 15 are fixed by a base end cap 16, which improves the stability of the frame demonstration.

[0014] As a preferred embodiment of the demonstrator, the ball receiving box guide block 8 has a cavity in the middle, and guide grooves are provided on both sides of the cavity. Guide rails 71 that are adapted to the guide grooves are provided on both sides of the ball receiving box. The guide rails 71 and the guide grooves are magnetically slidably attracted. An arc-shaped receiving groove 72 for receiving steel balls is opened on the top of the ball receiving box 7.

[0015] The principle of this demonstration is as follows: Place the demonstrator horizontally on a table, turn on the power to control the electromagnet assembly, and toggle the engagement switch to attract the steel ball to the electromagnet assembly. Attract steel balls of different masses to electromagnet assemblies at the same height, and toggle the engagement switch to the release position to release the steel balls, allowing them to fall freely. The steel balls strike the ball-receiving box below, and the gravitational potential energy of the balls of different masses at the same height is compared by comparing the displacement of the ball-receiving box during their fall. Then, attract steel balls of equal mass to electromagnet assemblies at unequal heights, and toggle the engagement switch to the release position to release the steel balls, allowing them to fall freely. The steel balls strike the ball-receiving box below, and the gravitational potential energy of the balls of the same mass at different heights is compared by comparing the displacement of the ball-receiving box during their fall.
