Abstract
The utility model discloses an Archimedes principle tester, comprising a bottom plate and a vertical plate vertically arranged on the bottom plate, wherein the bottom plate is provided with a transparent liquid containing cylinder with the top open and a measuring cup, the liquid containing cylinder contains water therein, the upper portion of the liquid containing cylinder is provided with an overflow tube, the water outlet of the overflow tube is located right above the measuring cup, a dynamometer is hung on the upper portion of the vertical plate, and a weight extending into the water inside the liquid containing cylinder is hung at the lower end of the dynamometer. The Archimedes principle tester is reasonable in design, simple in structure, easy in operation and high in accuracy, and is very visual, thereby being helpful for students to understand the Archimedes principle, and greatly increasing study positivity.
Description
Technical field
The utility model relates to a kind of education experiment equipment, relates in particular to a kind of Archimedes principle tester.
Background technology
Archimedes principle: be immersed in the suffered buoyancy of object in liquid, size equals it and arranges the suffered gravity of liquid.Archimedes principle is an important class in the middle of compulsory education curricular standard experiment textbook junior physics, at present, when the teacher of a lot of schools tells about this class journey on classroom, only that explanation is theoretical, students is listened to such an extent that be confused, without enough understanding, this do not have the uninteresting teaching of experimental apparatus can not play good teaching function.
The utility model content
The utility model, in order to solve weak point of the prior art, provides a kind of Archimedes principle tester that coordinates theory teaching.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the Archimedes principle tester, comprise base plate and the vertical riser be located on base plate, base plate is provided with open top and transparent knapsack and measuring cup, be loaded with water in knapsack, the top of knapsack is provided with overflow pipe, the overflow pipe water delivering orifice be positioned at measuring cup directly over, riser top is hung with dynamometer, and the dynamometer lower end is hung with and extend into undersurface weight in knapsack.
Adopt technique scheme, dynamometer is first measured the gravity G of weight in air
1, re-using dynamometer and hanging weight and be immersed into fully in water, the water in knapsack overflows and flows in measuring cup from discharger, and dynamometer is measured weight suffered gravity G in water
2, so just can calculate weight and be subject to buoyancy F upwards in water
Floating=G
1-G
2, according to the volume that spills into the water in measuring cup, can calculate G
Row, F
Floating=G
Row.Thereby draw Archimedes principle: be immersed in the suffered buoyancy of object in liquid, size equals it and arranges the suffered gravity of liquid.
The utility model is reasonable in design.Simple in structure, easy operating, degree of accuracy is high, has extremely strong intuitive, contributes to the student to understand Archimedes principle, has greatly improved the enthusiasm of Students ' Learning.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, Archimedes principle tester of the present utility model, comprise base plate 1 and the vertical riser 2 be located on base plate 1, base plate 1 is provided with open top and transparent knapsack 3 and measuring cup 4, is loaded with water 7 in knapsack 3, and the top of knapsack 3 is provided with overflow pipe 8, overflow pipe 8 water delivering orifices be positioned at measuring cup 4 directly over, riser 2 tops are hung with dynamometer 5, and dynamometer 5 lower ends are hung with and extend into the interior undersurface weight 6 of knapsack 3, and the density of weight 6 is greater than the density of water.
When experiment, first use dynamometer 5 to measure the gravity G of weight 6 in air
1, re-using dynamometer 5 and hanging weight 6 and be immersed into fully in water, the water in knapsack 3 overflows and flows in measuring cup 4 from discharger 5, and dynamometer 5 is measured weight 6 suffered gravity G in water
2, so just can calculate weight 6 and be subject to buoyancy F upwards in water
Floating=G
1-G
2, according to the volume that spills into the water in measuring cup 4, can calculate G
Row, F
Floating=G
Row.Thereby draw Archimedes principle: be immersed in the suffered buoyancy of object in liquid, size equals it and arranges the suffered gravity of liquid.
