Description
Technical field
The utility model relates to Physical Experiment apparatus field, especially a kind of physics teaching buoyancy experiment apparatus for demonstrating.
Background technique
The object being immersed in liquid or gas is called buoyancy by the power that liquid or gas are held in the palm straight up.The direction of buoyancy
With gravity direction on the contrary, straight up.Buoyancy Producing reason: the object in liquid or gas is immersed in by liquid or gas pair
The upward and downward pressure difference of object.The gravity that object arranges liquid in a liquid is equal to buoyancy suffered by object, i.e. F floats=ρ liquid
GV row.It usually requires to carry out buoyancy experiment aided education in this course teaching, to reinforce student's rational learning, current reality
It is relatively simple to test equipment, only beaker, spring scale, weight are tested, when hand-held spring scale is tested, hold it is unstable,
Weight can be up and down, influences gravity test result, and can only test weight, and the volume, that is, V row of weight in water is not
It can test, thus simple buoyancy effects demonstration can only be carried out, not can be carried out the calculating verifying of data, teaching efficiency is simultaneously paid no attention to
Think.
Summary of the invention
A kind of physics teaching is provided the purpose of this utility model is to overcome above-mentioned technical disadvantages to be demonstrated with buoyancy experiment
Device.It is simple to operate, it is rotated by screw rod and dynamometer is driven to move up and down, reading data is accurate, and weight is equipped with scale
