Virtual Lab - Spring Constant

An ideal spring obeys Hooke’s Law. Hooke’s Law states that the force from a spring is proportional to, and in the opposing direction to, the displacement of the free end. This can be written as

where F is the force imposed by the spring,
          d is the displacement of the free end of the spring,
          ks is known as the spring constant and,
          the minus sign indicates that the Force imposed by the spring is in the opposite direction to the displacement.

To conduct this virtual experiment;
         Click the buttons on the right to add the corresponding weight to the spring shown in the experimental image.
         Examine the extension of the spring, and tabulate your results in the table below, then click plot to plot your data.
