高中学生学科素质训练(高一物理测试题)（Discipline quality training for senior high school students (high physics test)） I carefully collated documents, documents from the network I only collect and sort out In case of error Please check it yourself! Discipline quality training for senior high school students (high physics test) Simple harmonic vibration First, the multiple-choice question 1. About harmonic vibration The following statements are true A. the greater the recovery force The speed must be greater B. restoring force is positive The speed must be negative C. restoring force is negative The acceleration must be negative D. restoring force may be the resultant force of some forces It can also be a component of some force 2, the spring oscillator acts as a simple harmonic motion along the straight line When the oscillator passes the same position two times in succession A. same acceleration Same kinetic energy B. has the same kinetic energy Same momentum C. restoring force is the same Mechanical energy and elastic potential energy are the same D. acceleration and displacement are the same Same speed 3, when the spring oscillator moves from the forward maximum displacement to the negative maximum displacement When two positions are symmetrical with the balance position What is correct is that... A. same acceleration The kinetic energy is the same as that of B. kinetic energy Same momentum C. restoring force is the same The mechanical energy is the same as that of D. acceleration Same speed 4. The correct version of the spring oscillator is that The period of A. is independent of amplitude The period of B. is related to amplitude The smaller the amplitude The smaller the cycle The C. is in the balance position and the speed is maximum D. at the maximum displacement It is at equilibrium because the speed is zero 5, the spring vibrator is a simple harmonic vibration Successively through the same momentum, through A, B two points Lasted 1 second After passing through the B point, th
