同学们在学习简谐运动时常出现一些错误的认识,大致有以下几点,请注意辨析.一、误认为机械振动一定是简谐运动物体在平衡位置附近所做的往复运动,叫做机械振动.振动是一种普遍的运动形式,大至地壳振
Students often learn some simple mistakes when learning simple harmonic motion, roughly the following points, please pay attention to discrimination.A mistakenly believe that mechanical vibration must be simple harmonic motion objects in equilibrium position near the reciprocating motion, called mechanical vibration. Vibration is a common form of motion, ranging from crustal vibrations
