Study the simple harmonic oscillation in its characteristic of the spring oscillator; measure its oscillation period and calculate the coefficient of stiffness of the spring by means of theoretical equation and then make comparison between the measuring results carried out in two different methods.
Learn the characteristic and method of application of the integrated Hall switch, and then with which to accurately measure the oscillation period of the spring oscillator.
Verification of the Hooke law, measurement of spring coefficient of stiffness and observation of linear diameter of the spring and its influence on the coefficient of stiffness.
