Embodiment 1

[0027] see Figure 1~3 , an environment-friendly and durable physical acceleration experiment device, comprising a base 1 and a base 4, the base 4 is an annular plate, the top right side of the base 4 is evenly provided with a number of second support rods 8, all of the The top of the second support rod 8 is provided with a motion tube 9, and the motion tube 9 is a transparent glass tube. The fixed pulley 15 matched with the pipe 14, and the experimental mechanism that is respectively matched with the fixed pulley 15 and the vertical pipe 14 are arranged in the moving pipe 9. The vertical pipe 14 is a transparent glass tube. By setting the moving pipe 9, the experimental mechanism is greatly reduced movement friction, thereby reducing the impact of friction on the experimental data and improving the accuracy of the experimental data; and using the vertical tube 14 to block the impact of the wind on the weight 16 and the wire rope 13, further reducing external influencing facto...

Embodiment 2

[0029] The present embodiment is a further elaboration on the basis of Embodiment 1. The experimental mechanism includes an experimental dolly 10 and a dotting timer 7. The experimental dolly 10 is arranged in the motion tube 9, and the right side end of the experimental dolly 10 is fixedly connected. Wire rope 13, the other end of the wire rope 13 is fixedly connected with the weight 16 matched with the vertical pipe 14 through the fixed pulley 15, and the wire rope 13 is pulled by the weight 16, thereby driving the experimental trolley 10 along the motion pipe 9 Make an accelerated linear motion to the right.

[0030] The dotting timer 7 is located on the left side of the motion tube 9, the dotting timer 7 is fixedly connected to the left side of the top of the base 4 by the first support rod 6, and the dotting timer 7 is connected to the experimental dolly 10 by a paper tape 11. On the left side, when the experimental trolley 10 accelerates to the right in a linear motion, ...

Embodiment 3

[0033] This embodiment is a further elaboration on the basis of Embodiment 1. A number of electric telescopic devices 2 are uniformly arranged on the left side of the top of the base 1, and the top ends of the telescopic rods 3 on the electric telescopic devices 2 are fixedly connected to the base. The bottom end of the seat 4 extends or retracts the telescopic rod 3 through the electric telescopic device 2, and then adjusts the height of the base 4, so as to adjust the height of the entire experimental device, which is convenient for experimenters of different heights to use, and improves the practicality of the entire experimental device. convenience.

[0034] The right side of the top of the base 1 is provided with a receiving box 18 matched with the vertical pipe 14, the receiving box 18 is an open top structure, and the inner cavity of the receiving box 18 is provided with a crash pad 19. The crash pad 19 is made of sponge material, receives the weight 16 falling from the...

Abstract

The invention provides an environmentally-friendly durable physical acceleration experimental device, and particularly relates to the technical field of physical experimental devices. The device comprises a seat and a base, a plurality of second support rods are evenly arranged on the right side of the top end of the base, the top ends of the second support rods are provided with movement tubes, the movement tubes are transparent glass tubes, the right ends of the movement tubes are communicated with vertical tubes, the right sides of the bottom walls of inner cavities of the movement tubes are provided with fixed pulleys matched with the vertical tubes, the movement tubes are internally provided with experimental mechanisms respectively matched with the fixed pulleys and the vertical tubes, and the vertical tubes are transparent glass tubes; the movement tubes are set to greatly reduce the rolling friction of an experimental trolley, thereby reducing the influence of the friction on the experimental data and improving the accuracy of the experimental data; the vertical tubes are used for blocking the influence of the wind on weights and wire ropes, external influence factors are further reduced, and the accuracy of experiments is improved; through a receiving box, the loss of the weights and collision damage can be prevented to the maximum extent, and the service life of the experimental device is prolonged.

Description

technical field [0001] The invention relates to the technical field of physical experiment devices, in particular to an environment-friendly and durable physical acceleration experiment device. Background technique [0002] Physics is a subject that studies the most general laws of motion of matter and the basic structure of matter. Its theoretical structure fully uses mathematics as its working language, and experiments are the sole criterion for testing the correctness of the theory. It is the most sophisticated natural science discipline today. [0003] The research of physics is based on experiments, and the teaching of physics is accompanied by a large number of teaching demonstration experiments. Intuitively prove the correctness of physical principles to students, thereby arousing students' interest in exploration and active learning, and improving teaching quality. In the teaching of physics experiments, the acceleration experiment is an important experiment in phy...
