The gradient of the graph of force F, (y-axis), and extension e, (x-axis), is equal to the spring constant k. Hooke’s Law is obeyed up to the limit of proportionality.

3: this is the spring constant from previous experiment. 8: I put the mass at about the same location below the spring as in the video. 15: this line creates a graph.

The spring constant, k, is different for different objects and materials. It is found by carrying out an experiment. ... Graph showing Hooke's Law, extension is plotted against force.

From the slope of the linear fit, this spring has a constant of around 8.6 newtons per meter—even after getting partially destroyed. Really, this is great. You know students in physics lab abuse ...
