Description
Technical field
The present invention relates to physics teaching aid field, specifically a kind of physics teaching exhibiting device.
Background technology
Elastic force is also known as " elastic force ".After object is deformed upon by external force effect, if removing external force, object can reply original shape
The power of shape, it is called " elastic force ".Its direction with make object produce deformation external force it is in opposite direction.Because the deformation of object have it is a variety of
It is various, so caused elastic force also has a variety of forms.For example, a weight is placed on plastic plate, the plastics being bent will
Restore to the original state, produce upward elastic force, here it is its holding power to weight.One object is hung on spring, object is spring
Elongate, the spring being elongated will restore to the original state, and produce upward elastic force, here it is its pulling force to object.Not only plastics, spring
Etc. that can deform upon, any object can deform upon, and the object not deformed upon is not present.But with deformation
It is obvious, can directly it see；Some deformation is quite small, it is necessary to just can perceive out with instrument.
At present, in physics teaching practice, many concepts and law are required for being demonstrated by testing on textbook
With demonstration, so needing to do many experiments in physical teaching course, learned with meeting that student more intuitively understands and grasped
Knowledge, in the teaching to the elastic deformation of spring and elastic force, due to no intuitively demonstration instrument, what teacher can only be abstracted says
Solution, student's indigestion, effect of giving lessons is poor, and it is more difficult that student understands, theory explaination can not allow student intuitively to observe the big of pulling force
The small influence to camber of spring, and the size of elastic force caused by camber of spring；In existing device, in terms of elastic force
