论文部分内容阅读
机械振动和机械波是日常生活中常见的两种运动形式,它综合了运动学、动力学和能量转化与守恒等知识,是每年高考的必考内容。同时这部分内容还是学好交变电流、电磁波、光波等内容的前提。在高考中命题频率最高的知识有:波的图象、振动图象、频率、波长和波速的关系、单摆的周期
Mechanical vibration and mechanical waves are two common forms of exercise in daily life. It integrates knowledge of kinematics, dynamics, and energy conversion and conservation. It is a mandatory examination content for the annual college entrance examination. At the same time, this part is still a prerequisite for learning about alternating currents, electromagnetic waves, and light waves. The highest frequency of propositional knowledge in the college entrance examination is: the relationship between the wave image, the vibration image, the frequency, the wavelength and the wave velocity, and the period of the pendulum.
