Embodiment 1
[0013] A multifunctional experimental device for centrifugal movement, such as figure 1 , figure 2 , image 3 As shown, it includes: demonstration object 4; the centrifugal motion multifunctional experimenter also includes a motor 1, a demonstration disk 3; the lower surface of the demonstration disk 3 is horizontally fixed on the shaft of the motor 1, and the demonstration object 4 is placed on the upper surface of the demonstration disk 3. Top; The centrifugal motion multifunctional experimenter also includes a demo disk cover 5, which is fixed on the demo disk 3, and the demo disk cover 5 buckles the demo disk 3 into it.
[0014] Place the demonstration objects of different qualities on the same radius near the center of the upper surface of the demonstration disc, fasten the demonstration disc cover tightly on the demonstration disc, turn on the motor, and observe the demonstration objects on the demonstration disc through the demonstration disc cover. Take a look Who moves f...
Embodiment 2
[0017] A multifunctional experimental device for centrifugal movement, such as figure 1 , As shown in Figure 4, which includes: demonstration object 4; the centrifugal motion multi-function experiment device also includes motor 1, traction wire 8, sliding rheostat 2, demonstration disk 3; the center of the demonstration disk 3 has a raised axon; traction wire One end of 8 is fixedly connected to the demonstration object 4, and the other end of the pulling wire 8 is fixedly connected to the axon; the pulling wire 8 is an elastic pulling wire; the sliding rheostat 2 is connected in parallel with the motor 1.
[0018] One end of the traction wire is fixedly connected to the demonstration object, and the other end of the traction wire is fixedly connected to the axon. Adjusting the sliding rheostat can change the speed of the motor. Therefore, it can be observed that the length of the traction line also changes. The centripetal force also changes.
[0019] The advantages of the prese...
Embodiment 3
[0021] A multifunctional experimental device for centrifugal movement, such as figure 1 , As shown in Figure 5, which includes: demonstration object 4; the centrifugal motion multifunctional experiment device also includes motor 1, traction wire 8, sliding rheostat 2, demonstration plate 3, spring scale 9; the lower surface of demonstration plate 3 is fixed horizontally on motor 1 On the shaft, there is a convex axon in the center of the demo disk 3, a top hole 6 on the upper surface of the axon, a wall hole 7 on the side wall of the axon, and the wall hole 7 and the top hole 6 communicate in the axon; the spring scale 9 One end is fixedly connected to one end of the traction line 8. The traction line 8 passes through the top hole 6 and the wall hole 7 of the axon on the demonstration disk 3, and the other end of the traction line 8 is fixedly connected to the demonstration object 4; the traction line 8 is an inelastic traction line; The varistor 2 is connected in parallel with t...
