Abstract
The utility model discloses a physics teaching aid. The physics teaching aid comprises a ball storage barrel with scale marks, wherein steel balls are arranged in the ball storage barrel, and a U-shaped magnet is arranged outside the ball storage barrel. During use, an external force is applied on the U-shaped magnet by virtue of the mutual attraction between the U-shaped magnet and the steel balls, and then an equal-speed and same-direction movement between the U-shaped magnet and the steel balls can be realized. With the adoption of the physics teaching aid disclosed by the utility model, demonstration and explanation for the equal-speed and same-direction movement of different objects in physics teaching become very simple and visual, so that the operation of a teacher is facilitated, and the understanding of students is promoted.
Description
Technical field
The utility model relates to teaching device therefor field, especially a kind of physics teaching teaching aid.
Background technology
In the physics lesson teaching now, the explanation of speed motion together in the same way is generally all comparatively abstract between the object, student's indigestion, and different objects applied corresponding external force, realizing them aspect fast motion, instructors is difficult grasp also.
The utility model content
The utility model technical assignment is at not enough in the above-mentioned technology, and a kind of physics teaching teaching aid is provided.
The technical scheme that the utility model technical solution problem adopts is: a kind of physics teaching teaching aid, comprise the ball storage barrel of being with scale mark, and be provided with steel ball in this ball storage barrel, be provided with U-shaped magnet in this ball storage barrel outside simultaneously.
The beneficial effect that the utility model can bring is: make different objects in the physics teaching, same speed, homodromous demonstration and explanation to become very simple and easy, vivid, be convenient to operation of teacher, also be beneficial to the student and understand.
Description of drawings
Fig. 1, the utility model one-piece construction synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done following detailed description:
As shown in Figure 1, a kind of physics teaching teaching aid that the utility model is announced, comprise the ball storage barrel 1 of being with scale mark, be provided with steel ball 2 in this ball storage barrel 1, simultaneously be provided with U-shaped magnet 3 in this ball storage barrel 1 outside, during use, utilize the power that attracts each other between U-shaped magnet 3 and the steel ball 2, U-shaped magnet 3 is applied external force, can realize same speed, motion in the same way between U-shaped magnet 3 and the steel ball 2, the utility model makes and different objects in the physics teaching, same speed, homodromous demonstration and explanation becomes very simple and easy, vivid, be convenient to operation of teacher, also be beneficial to the student and understand.
