Abstract
The utility model comprises a force transducer and a device body. The device body is hitched on the force transducer by hitch components. The device body is provided with a weight collision block which can make falling movement by self gravity. The bottom of the device body is connected with a base which picks up the weight collision block. The device body is also provided with a buffer element with replaceable buffer material. The beneficial effects of the utility model: the device can better reflect the relationship between the intensity of the impact and the buffer substance during collision process and verify momentum theorem; the device can well explain that the impact is different but the impulse is equal when the collision occurs in the same distance in a physical test; the device has simple structure, low fabrication cost and good use effect.
Description
Technical field
The utility model relates to a kind of experimental provision, especially a kind of collision and buffering experimental provision.
Background technology
At present, when in middle school physical experiment, cooperating the concerning of impulse force size and cushion in " Vernier LabPro " digital experiment systematic study collision process, do not have suitable experimental provision, be not easy to teaching.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and the relation of the size of impulse force in a kind of Reactive Collisions process with cushion is provided, and the experimental provision of checking theorem of momentum.
The utility model solves the technical scheme that its technical matters adopts: this collision and buffering experimental provision, comprise force transducer, apparatus main body, apparatus main body is hung on the force transducer by suspender, apparatus main body is provided with the weight Impactor that can rely on himself gravity to do motion, and the bottom of apparatus main body is connected with the base of accepting the weight Impactor; Also be provided with the bolster of replaceable padded coaming on the apparatus main body.
The effect that the utility model is useful is: this device is the relation of impulse force size and cushion in the Reactive Collisions process preferably, and the checking theorem of momentum.Can well illustrate in the Physical Experiment, in the collision that same distance takes place, the impulse force difference, but momentum equates.Simple in structure, low cost, result of use is good.
