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.
