A linear spring of force constant k is used in physics lab experiment. A block of mass m is attached to the spring and the resulting frequency, f, of the simple harmonic oscillation is measured. Blocks of various masses are used in different trials, and in each case, the corresponding frequency is measured and recorded. If f² is plotted versus 1/m, the graph will be a straight line with slope

• 4π²/k

• (4π)(2k)
