Abstract
The utility model provides a kind of centripetal force demonstrator of relation between the related physical quantities such as a kind of demonstration centripetal force size that can be visual in image and mass of object, linear velocity, radius, including weight beam, transparent plastic sheet, lightweight fine rule, prill, base, it is simple in construction, it is convenient and practical.
Description
Technical field
A kind of physical teaching aid is the utility model is related to, is particularly used for demonstrating centripetal force size and mass of object, line
The teaching aid of relation between the related physical quantities such as speed, radius.
Background technology
At present, the demonstration teaching aid of centripetal force has a variety of in physics teaching, but has that structure is relatively complicated, and demonstrating effect is not
The problems such as enough visual patterns.
Utility model content
In order to overcome the above insufficient, the utility model provides a kind of demonstration centripetal force size that can be visual in image and object
A kind of centripetal force demonstrator of relation between the related physical quantities such as quality, linear velocity, radius.
Technical scheme is used by the utility model solves its technical problem：A kind of centripetal force demonstrator is surveyed including spring
Power meter, transparent plastic sheet, lightweight fine rule, prill, base, it is that outside is transparent cylinder the characteristics of the weight beam,
Stand upside down and place, its spring section is placed in bottom, tuning drive gear is fixed with spring top, and graduation mark is placed in top, graduation mark two
The length value of the other data and spring elongation for marking power successively from top to bottom, weight beam top are fixedly connected on transparent
Plastic plate center, the transparent plastic sheet centre bit are equipped with aperture, lightweight fine rule one end connecting spring dynamometer inside bullet
Spring top dead center position, the other end connect prill by transparent plastic sheet central small hole, and the middle of the base has neck, use
In being fixedly connected with weight beam bottom.
Further, the transparent plastic sheet is circle, and surface is smooth.
Further, the prill is drilled with aperture, convenient to connect lightweight fine rule, and prill has different quality type
It is available for exchanging.
The beneficial effects of the utility model are：Prill does steady circular's fortune on glossy clear plastic plate in the present apparatus
When dynamic, by lightweight fine rule connecting spring dynamometer, can size and the mass of object of visual in image demonstration centripetal force, linear velocity,
Relation between the related physical quantities such as radius, it is simple in construction, it is convenient and practical.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
It is as follows to correspond to label for component names in figure：1st, weight beam；2nd, transparent plastic sheet；3rd, prill；4th, lightweight
Fine rule；5th, base；11st, graduation mark；12nd, pointer；13rd, spring；21st, aperture；51st, neck.
