Abstract

The invention discloses a buoyancy demonstration device based on physics teaching. A seat plate is included; two plug bushes are welded at the top end of the seat plate; a weighing cup is placed on one side of the top end of the seat plate; scales are arranged on one side of the weighing cup; a screw rod is rotationally mounted on one side of the top end of the seat plate through a bearing; a guide rod is further welded to one side of the top end of the seat plate; the screw rod is movably provided with a supporting arm through a thread; the guide rod penetrates through the supporting arm; theguide rod and the supporting arm are movably installed, the horizontal portion of one end of the supporting arm extends into the weighing cup, a connecting rod is movably arranged at the horizontal portion of one end of the supporting arm in a penetrating mode, a contact piece is fixedly installed at the vertical portion of one end of the supporting arm through a screw, a contact block is fixedlyinstalled at one end of the connecting rod, and the contact block is located below the contact piece. The buoyancy demonstration device is reasonable in design structure, simple to operate, convenient to use, capable of verifying the Archimedes principle and more accurate in data.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a buoyancy demonstration device based on physics teaching. Background technique [0002] Buoyancy refers to the difference (combined force) between the pressure of the fluid (liquid and gas) on each surface of an object in a fluid (including liquid and gas). Archimedes' principle: The object immersed in the liquid is subjected to upward buoyancy force, and the buoyancy force is equal to the gravity of the object displacing the liquid, that is, F float = G liquid discharge = ρ liquid gV discharge. (V row indicates the volume of liquid displaced by the object) The direction is vertically upward and passes through the centroid of the displaced fluid. In the physics classroom, in order to better demonstrate Archimedes' law, some devices are needed to demonstrate, but the existing teaching devices cannot be well displayed. Contents of the invention [0003] The purpose...
