Abstract
The utility model discloses an inertia demonstration trolley characterized in that wheels are respectively arranged at the four corners of the bottom part of a square trolley surface; the upper part of the square trolley surface is provided with a support; the middle of the upper part of the support is provided with a cylinder which is open at the both ends; a bottom barrel is arranged on the square trolley surface; a hook is arranged at one side of the support; and an iron ball is hung inside the cylinder through a lifting rope. By virtue of the aforementioned arrangements, the inertia demonstration trolley is capable of demonstrating the fact that an object can maintain an original motion state due to inertia in the process of uniform motion during the teaching of physics, thereby helping students to understand the concept of inertia in the physics learning.
Description
Technical field
The utility model relates to a kind of physics teaching demonstration teaching aid, is a kind of inertia demonstration trolley of demonstrating the inertia fundamental property specifically.
Background technology
Have now in the physics educational apparatus, the fundamental property of inertia when only having the demonstration object static, and lack the teaching aid that inertia shows when demonstrating object of which movement, the teacher can only in the explanation of blackboard picture, waste time and energy, and the student be difficult for understand and master when explanation.
Summary of the invention
The purpose of this utility model is to provide a kind of can demonstrate out moving object owing to the inertia demonstration trolley of the original motion state of inertia energy maintenance.
To achieve these goals, four jiaos in the bottom of square car face of the utility model are respectively equipped with wheel, top at square car face is provided with support, be provided with the cylinder of a upper and lower opening in the middle part, top of support, be provided with an end cylinder at square car face, cylinder of the described end is vertically corresponding mutually with cylinder, hook is located at a side of support, one end of lifting rope is connected with little iron ball, and the other end is connected with hook, and little iron ball is suspended in the cylinder.
By above setting, when the utility model can be demonstrated the object uniform motion in physics teaching, because inertia energy keeps original motion state, be conducive to break through the Physics Learning middle school student to the understanding of this concept of inertia.
Description of drawings
Now by reference to the accompanying drawings the utility model is described further.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, square car face, 2, wheel, 3, support, 4, cylinder, 5, end cylinder, 6, hook, 7, lifting rope, 8, little iron ball.
Embodiment
As shown in Figure 1, four jiaos in the bottom of square car face 1 of the utility model are respectively equipped with wheel 2, be provided with support 3 on the top of square car face 1, be provided with the cylinder 4 of a upper and lower opening in the middle part, top of support 3, be provided with an end cylinder 5 at square car face 1, cylinder 5 of the described end is vertically corresponding mutually with cylinder 4, hook 6 is located at a side of support 3, one end of lifting rope 7 is connected with little iron ball 8, and the other end is connected with hook 6, and little iron ball 8 is suspended in the cylinder 4.By above setting, pulling the utility model is made linear uniform motion, rapidly lifting rope 7 is cut off, and can see that little iron ball 8 falls into end cylinder 5.When the object uniform motion can be described, because inertia energy keeps original motion state.
