Finally, Hookes law assumes an ideal spring. Part of this definition is that the response of the spring is linear, but its also assumed to be massless and frictionless. Hooke's Law Calculator - Spring Constant Calculator F = 2N. Figure 2: The apparatus setup for the Hooke's . Spring constant is a characteristic of a spring which measures the ratio of the force affecting the spring to the displacement caused by it. How to find the spring constant (example problem) F = mg = (250 kg)(9.8 m/s 2) = 2,450 N. where F equals force, m equals the mass of the object, and g equals the acceleration due to gravity, 9.8 meters per second 2. The spring constant, k, is representative of how stiff the spring is.Stiffer (more difficult to stretch) springs have higher spring constants. Yes, rubber bands obey Hooke's law, but only for small applied forces. However, if you know the elastic potential energy and the displacement, you can calculate it using: In any case youll end up with a value with units of N/m.
