Abstract

The invention discloses a buoyancy demonstration teaching aid for physical experiments, which comprises an operating table, and two containers are arranged on the top of the operating table. In the present invention, under the action of spring 2, the rubber block is closely attached to the side wall of the column, and the sliding sleeve is fixed, and the end of the sliding sleeve is at the same height as the initial liquid levels of liquid medium 1 and liquid medium 2. When the pull ring is pulled and the limit pin is separated from the limit groove, under the action of the gravity of the floating block, the turntable rotates, the moving block moves inside the arc groove, the moving block moves to both sides of the horizontal plate one, and the two float The blocks fall into the inside of the two containers respectively, and the floating block floats on the liquid surface of liquid medium 1 and liquid medium 2. By observing the rising height of liquid medium 1 and liquid medium 2, it can be more intuitively and visually verified that the objects are When the buoyancy force is constant, the inference that the displacement of objects in liquids of different densities is different is helpful for teachers' teaching and students' learning of the principle of buoyancy.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a buoyancy demonstration teaching aid for physical experiments. Background technique [0002] The force exerted on an object submerged in a fluid by the fluid to lift it up is called buoyancy. Buoyancy refers to the difference (resultant force) of the fluid pressure on each surface of an object in a fluid (liquid and gas). In 245 BC, Archimedes discovered the principle of buoyancy. The definition of buoyancy is F float = G row (that is, the buoyancy on the object is equal to the gravity of the liquid displaced after the object sinks and rests), and it can be used for calculation to derive the formula F float = ρ liquid gV row (ρ liquid represents the density of the liquid , the unit is kilogram / cubic meter; g represents a constant, which is the ratio of gravity to mass, g=9.8N / kg can be roughly calculated as 10N / kg; row V represents the volume of the displaced liquid, and...
