The gradient of the line \(\frac{\text{F}}{\text{e}}\) is the spring constant, k. Key fact The gradient of the graph of force F, (y-axis), and extension e, (x-axis), is equal to the spring constant k.

Plot a graph of stretching force ... beyond the limit of proportionality and it stretches by 15 cm. Calculate the spring constant. The unloaded length of a spring is measured.

For this particular spring, this constant would have ... 15: this line creates a graph. The data points are added to this plot in line 23. 19: here I calculate the force. Notice that I don't ...

I know it is difficult to read the slope from that graph, so I will just tell you what is there. For one spring by itself, the slope (and thus the spring constant) is 5.289 N/m. The two springs in ...
