Abstract
The utility model discloses a physics teaching resonance pendulum, characterized in that an upper portion of a base is provided with a support; an upper portion of the support is inserted by a rectangular swing arm; a pendulum ball is arranged at one end of the rectangular swing arm; the rectangular swing arm in the support intermediate part clamps four small balls with different pendulum lengths side by side through spring clips. According to the arrangement, the physics resonance pendulum has a simple structure; when a teacher is explaining the physical resonance knowledge, the physics teaching resonance pendulum is visual for teaching and convenient to change pendulum length, thereby changing frequency and providing convenience for students to understand and grasp the resonance knowledge.
Description
Technical field
The utility model relates to a kind of physical teaching aid, is a kind of physics teaching resonance pendulum specifically.
Background technology
In physics teaching in secondary school, the resonance partial content is the more not wield part of student's ratio, the teacher is in the explanation process, to be difficult to the image explanation, add traditional lecture experiment teacher and be not easy to operation, especially the student who does not have experience of life wants to understand principle wherein, and forming pure and fresh understanding in brain is not an easily thing.
Summary of the invention
The purpose of this utility model is that a kind of physics teaching resonance pendulum in the convenient demonstration of Physics Classroom is provided.
To achieve these goals, the utility model is provided with support on the top of base, be interspersed with rectangular-shaped swing arm on the top of support, swing ball is located at an end of rectangular-shaped swing arm, accompanies side by side four beads that pendulum length is different by spring clip in the rectangular-shaped swing arm in the middle of the support.
By above setting, the utility model is simple in structure, and the teacher imparts knowledge to students intuitively, is convenient to change the pendulum length of pendulum, thereby reach the purpose that changes frequency when explanation physical resonant vibration knowledge, makes the student be convenient to understand and grasp the knowledge that resonates.
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, base, 2, support, 3, rectangular-shaped swing arm, 4, swing ball, 5, spring clip, 6, bead.
Embodiment
As shown in Figure 1, the utility model is provided with support 2 on the top of base 1, be interspersed with rectangular-shaped swing arm 3 on the top of support 2, swing ball 4 is located at an end of rectangular-shaped swing arm 3, accompanies side by side four beads 6 that pendulum length is different by spring clip 5 in the rectangular-shaped swing arm 3 in the middle of the support 2.By above setting, the utility model uses the swing of swing ball 4 as drive force source, allow rectangular-shaped swing arm 3 drive four different beads 6 of pendulum lengths and swing, can observe the successively variation of different bead 6 amplitudes of four pendulum lengths, observe successively the resonance effect of bead 6.Change the position of swing ball 4, larger variation has occured in the amplitude that can observe significantly the different bead 6 of four pendulum lengths, thereby makes the student recognize that intuitively the amplitude of forced vibration is relevant with the frequency of driving force, and experiment effect is better.
