The experiment was designed to verify hooke's law, with the aim of exploring the quantitative relationship between spring force and spring elongation, and learning the scientific method used.
The existing experimental equipment comprises two springs (one of the springs is thicker and shorter, and is suitable for being used for experiments of spring shortening, the spring is not too soft so as to prevent the spring from exceeding the elastic limit of the spring when being stretched), five weights with the same mass, five groove codes with the same mass, one millimeter scale and one iron stand (used for hanging the spring).
The experimental steps are as follows:
(1) a thin spring is suspended on an iron stand. The length l0 of the spring is measured out with a millimeter scale and filled into a table.
(3) As shown, 1 hook code is hung under the spring, and the length l of the spring is measured out by a millimeter scale and filled in a table.
(4) Respectively hanging 2, 3, 4 and 5 same hook codes under the spring, measuring out the corresponding spring length l in sequence, and filling the spring length l into a watch.
(5) The elongation (l-l 0) of the spring when 1, 2, 3, 4 and 5 hooks are hung under the spring is calculated respectively and filled in a watch.
(6) The force is used as the ordinate, the elongation of the spring is used as the abscissa, and points are drawn on the coordinate paper according to the measured data in the table.
Because the spring hangs on the iron stand among the current experimental method, and the weight is established to the back string, because the weight drops when hanging to establish and causes the spring swing, just can measure when needing the spring static when measuring the spring, measure moreover and be accurate inadequately.
