Abstract
The present invention relates to a multifunctional experimental instrument for centrifugal motion, which can be used for accurately demonstrating teaching experiments of centrifugal force and centripetal force of objects. The present invention comprises demonstration objects, a motor and a demonstration disk, wherein the lower surface of the demonstration disk is horizontally fixed on a shaft of the motor, and the demonstration objects are arranged on the upper surface of the demonstration disk. The present invention has the advantages that because the present invention is provided with the motor and the demonstration disk, the lower surface of the demonstration disk is horizontally fixed on the shaft of the motor, the demonstration objects which have different weights are arranged on the demonstration disk, the motor is started up, and the demonstration is clearly demonstrated. Because the demonstration objects which have large weights have large centrifugal force, and the demonstration objects which have large weights are firstly moved to the edges of the demonstration disk.

Fig. 2 is a kind of structural representation of the present invention;
Fig. 3 is the vertical view of Fig. 2;
Fig. 4 is another kind of structural representation of the present invention;
Fig. 5 is the third structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
A kind of multifunctional experimental equipment for centrifugal motion, as Fig. 1, Fig. 2, shown in Figure 3, comprising: demonstration thing 4; This multifunctional experimental equipment for centrifugal motion also comprises motor 1, demonstration board 3; Demonstration board 3 lower surfaces are horizontally fixed on the axle of motor 1, and demonstration thing 4 places on demonstration board 3 upper surfaces; This multifunctional experimental equipment for centrifugal motion also comprises demonstration disk cover 5, and demonstration disk cover 5 is fixed on the demonstration board 3, and demonstration disk cover 5 buckles into demonstration board 3 wherein.
The demonstration thing of different quality is placed near the demonstration board upper surface center the same radius, will demonstrate disk cover and be held on the demonstration board, start motor, can observe demonstration thing on the demonstration board by the demonstration disk cover, it is moving earlier whom has a look at.Do not need to use slide rheostat among this embodiment.
Advantage of the present invention is: because the present invention is equipped with motor, demonstration board; The demonstration board lower surface is horizontally fixed on the axle of motor, and the demonstration things that quality is different place on the demonstration board, starts motor and can demonstrate out clearly owing to the big demonstration thing centrifugal force of quality is big, moves to the demonstration board edge at first.
A kind of multifunctional experimental equipment for centrifugal motion, as Fig. 1, shown in Figure 4, comprising: demonstration thing 4; This multifunctional experimental equipment for centrifugal motion also comprises motor 1, draught line 8, slide rheostat 2, demonstration board 3; There is the aixs cylinder of projection at demonstration board 3 centers; The fixedly connected demonstration thing 4 of draught line 8 one ends, draught line 8 other ends are fixedly connected on the aixs cylinder; Draught line 8 is the elastic traction line; Slide rheostat 2 is in parallel with motor 1.
With the fixedly connected demonstration thing of draught line one end, the draught line other end is fixedly connected on the aixs cylinder, regulates slide rheostat and can change rotating speed of motor, and the length that therefore can be observed draught line also changes, hence one can see that because the change of rotating speed, and the centripetal force of demonstration thing also changes.
Advantage of the present invention is: because the present invention has also designed motor, draught line, slide rheostat; Slide rheostat and motor also connect; The fixedly connected demonstration thing of draught line one end, the draught line other end are fixedly connected on the axle of motor; Draught line is for being with flexible draught line among the present invention; Therefore the change of the rotating speed of motor length that can be observed draught line also changes, and hence one can see that because the change of rotating speed, and the centripetal force of demonstration thing also changes.
A kind of multifunctional experimental equipment for centrifugal motion, as Fig. 1, shown in Figure 5, comprising: demonstration thing 4; This multifunctional experimental equipment for centrifugal motion also comprises motor 1, draught line 8, slide rheostat 2, demonstration board 3, spring balance 9; Demonstration board 3 lower surfaces are horizontally fixed on the axle of motor 1, and there is the aixs cylinder of projection at demonstration board 3 centers, and the aixs cylinder upper surface has apical pore 6, and cinclides 7 is arranged on the aixs cylinder sidewall, and cinclides 7 and apical pore 6 communicate in aixs cylinder; Fixedly connected draught line 8 one ends of one end of spring balance 9, draught line 8 passes the apical pore 6 and the cinclides 7 of the aixs cylinder on the demonstration board 3, the fixedly connected demonstration thing 4 of draught line 8 other ends; Draught line 8 is nonelastic draught line; Slide rheostat 2 is in parallel with motor 1.
With fixedly connected draught line one end of an end of spring balance, draught line passes the apical pore and the cinclides of the aixs cylinder on the demonstration board, the fixedly connected demonstration thing of the draught line other end; Regulate slide rheostat scalable rotating speed of motor; Because the change of motor speed,, can on spring balance, observe the centrifugal force of demonstrating thing because of the change of demonstration thing rotating speed this moment and also change so the rotating speed of demonstration thing also changes.
Advantage of the present invention is: because the present invention also is designed with motor, draught line, slide rheostat, drills Show dish, spring scale; One end of spring scale is fixedly connected with draught line one end, and draught line passes on the demonstration board The apical pore of aixs cylinder and cinclides, the draught line other end is fixedly connected with the demonstration thing; Regulating slide rheostat can regulate The rotating speed of motor; Because the change of motor speed, so the rotating speed of demonstration thing also changes, this moment can be at bullet Observing the centrifugal force of demonstrating thing because of the change of demonstration thing rotating speed on the spring scale also changes.
