发明创造可以帮助我们从熟悉的事物中发现问题,从而进行改进。对于我们学生来说,最熟悉的莫过于学习了,学科实验中教具的发明既可以让学习变得更简单,又可以学以致用。简谐运动演示仪就是实验教具的一种。我们都知道,简谐运动是最基本也是最简单的机械振动,实际上就是正弦振动。它是一种由自身系统性质决定的周期性运动(如单摆运动和弹簧振子运动)。当某种物体进行简谐运动时,物体所受的力跟位移成正比,并且总是指向平衡位置。简谐运动的特点是:研究变力
Inventions can help us to identify problems from familiar things and make improvements. For our students, the most familiar thing is to learn, the invention of teaching aids in the subject experiment can make learning easier and learn. Simple harmonic motion demonstrator is a kind of experimental teaching aids. We all know that simple harmonic motion is the most basic and simple mechanical vibration, in fact it is a sinusoidal vibration. It is a periodic motion (such as pendulum motion and spring oscillator motion) that is determined by the nature of its own system. When a certain object performs simple harmonic motion, the force the object receives is proportional to the displacement, and always points to the equilibrium position. Harmonic movement is characterized by: research variable
