Abstract

The invention provides an experiment device for verifying that conservative force working has nothing to do with a path. A bottom plate is arranged at the lower part between two brackets; two ends ofthe bottom plate are fixedly connected with the opposite internal sides of the two brackets; at least two internal grooves are formed in the upper surface of the bottom plate; corresponding limiting blocks are correspondingly arranged at the upper parts of the opposite internal sides of the two brackets; a cross beam is arranged at the upper part between the two brackets, the cross beam is of a detachable structure, and two ends of the cross beam are erected on the limiting block; at least two through holes are formed in the cross beam; the through holes correspond to the internal grooves in the up-and-down direction; transparent pipelines are arranged between the through holes and the internal grooves; the transparent pipelines comprise linear pipes and curve pipes; working state displaypieces are arranged on the internal bottom surfaces of the transparent pipelines; and small balls are in contact with the working state display pieces. The experiment device for verifying that conservative force working has nothing to do with the path, provided by the invention, has the advantages that the structure is simple, the verifying process is visual and accurate, the operation is convenient, direct perceptual knowledge can be provided, the cost is low and the effect is good.

Description

technical field

[0001] The invention relates to a teaching tool, in particular to an experimental device for verifying that the work of a conservative force has nothing to do with the path in the teaching. Background technique

[0002] In daily life, the three known conservative forces are gravity, electric field force and elastic force. In the actual physics teaching process, when it is usually verified that the work of the above-mentioned known conservative force has nothing to do with the path, only relevant formulas are used for derivation, and there is no specific experimental device to carry out intuitive and comprehensive verification.

[0003] After retrieval, the Chinese patent "Demonstration Device Independent of Gravity Work and Path (ZL2010205345829)" discloses a demonstration device for verifying that gravity work is independent of path. Although the device specifically shows that the gravitational work of objects in different paths is the same, however, It als...
