2. The magnetic column began to fall when the weight passed the lowest point, but the length of the magnetic column was not long enough. After 0.2 seconds, it was obvious that the magnetic column fell down
Both of these statements sound plausible. It is a very complicated theoretical issue to use theoretical knowledge to determine which statement is correct.

Embodiment 1

[0031] See attached image 3 , is the front view of the present invention, attached Figure 4 is a side view of the present invention. Figure 5 is a side view of the present invention, in Figure 5 , enclosing a range with dotted lines, these ranges are in Figure 6 is shown enlarged in , or, Figure 6 yes Figure 5 A partial enlargement of the . These figures express:

[0032] The device used for vertical surface dynamics research includes a vertical panel 1, which is located at the lower end of the vertical panel 1 and is used to support the base 2 of the vertical panel 1. It is characterized in that: the vertical panel 1 is made of refractory material, and the vertical panel The panel 1 is fixedly connected with an adsorption plate 6 for absorbing the permanent magnet, and the surface of the adsorption plate 6 for absorbing the permanent magnet is a vertical plane,

[0033] It also includes a columnar magnetic column 3 made of permanent magnets, one end of the magne...

Embodiment 2

[0059] See attached Figure 7 , is the invention by the attached Figure 6 Optimized technical solutions. It also includes: taking the vertical plane passing through the thin line 4 as a plane of symmetry, and a second nozzle 9 symmetrically arranged with the first nozzle 8, and the fire spraying direction of the second nozzle 9 is: both vertical to the vertical panel 1, and vertical in thin line 4.

[0060] Only one nozzle is used to burn the thin wire 4, and there is a shortcoming: the ejected flame will make the thin wire 4 receive a small impulse, and the direction of this impulse is perpendicular to the vertical panel 1 and away from the vertical panel 1. Even so, Still let some observers (students) raise doubts, they think, be that the impulse that flame exerts on thin wire 4 has influenced the stressed of thin wire 4, and then, thin wire 4 pulls down magnetic column 3. There is some truth to this claim: because the flames did give the thin line 4 an impulse, albeit a...

Embodiment 3

[0063] See attached Figure 8 , the shape of the hole 7 is: arc shape, and the hole 7 of the arc shape is located above the weight 5 . One advantage of this design is that the position of the fire point can be adjusted. And the center of the arc is located at the junction of the magnetic column 3 and the adsorption plate 6, and the radius of the arc is slightly smaller than the length of the rope. Slightly smaller than—these three words are generally unclear, but in this application, slightly smaller means that the position where the thin wire 4 is blown is preferably close to the position of the weight 5 . The thin wire turns at the same angle, and the farther it is from the center of the circle, the longer the arc length it travels. If the thin wire is burnt at a position very close to the center of the circle, the deflection angle of the thin wire may be too large. For this understanding, please refer to the explanation of the word "approach" in this specification.

Abstract

The invention discloses the field of devices for vertical face kinetic studies, and particularly relates to a kinetic device involved in circling motion studies. A weight tied by a string does circling motion on a vertical plane, the situation that an experiment phenomenon does not accord with the theory occurs, and the device is provided in order to explain the phenomenon and prove the accuracy of the theory. The device for the vertical face kinetic studies comprises a vertical face plate and is characterized in that the vertical face plate is fixedly connected with an attracting plate for attracting a permanent magnet; a magnetic column is further included, one end of the magnetic column is attracted to the attracting plate, the other end of the magnetic column is tied by the string, the upper end of the string is in tied connection with the magnetic column, and the weight is hung at the lower end of the string; a hole penetrating through the front face and the back face of the vertical face plate is formed in the vertical face plate, a first nozzle used for spitting fires so that the string can be burnt out as early as possible after the string deviates from the balance position is arranged in the hole, and the fire spitting direction of the first nozzle is perpendicular to the vertical face plate and the string.

Description

[0001] This application is a divisional application of the invention patent application with the application number 2015100510598, the invention name is a device for vertical surface dynamics research, and the application date is 2015-01-30. technical field [0002] The invention belongs to the field of devices used for vertical surface dynamics research, in particular to the dynamics device involved in the research of circular motion. Background technique [0003] A thin wire is tied to a heavy object to move in a circle on a vertical plane. When the weight is at its lowest point, the pulling force is greater than gravity, and the pulling force at the lowest point is the largest. The prior art discloses a device for studying circular motion: a vertical panel, located at the lower end of the vertical panel for supporting the base of the vertical panel, the vertical panel is made of iron plate, and also includes a permanent magnet, shaped It is a columnar magnetic column, one...
