To state the restoring force of a simple pendulum during oscillation is the resultant force of the gravity of the ball and the pulling force of the thread is wrong .
常出现一些模糊认识,即认为单摆在振动中所受的回复力就是摆球所受重力与绳子拉力的合力,显然,这是错误的。
Using the single pendulum, we can research the relationship between the period of oscillation of it and the length of it and measure local acceleration of gravity.
通过单摆装置可以方便地研究单摆的振动周期与摆长关系和测定当地的重力加速度。
