Experiment to Investigate the Relationship Between Extension and Applied Force on a Spring

The video tutorial explains an experiment to investigate the relationship between the force applied to a spring and its extension. It outlines the procedure, including suspending the spring, measuring its extension, and adding masses. The experiment's variables are defined, and results are plotted on a graph to determine the spring constant. The relationship between force and extension is shown to be proportional up to a certain limit, and the spring constant is calculated using the graph.

What are the independent, dependent, and control variables in the spring extension experiment?

How do you calculate the spring constant from the graph of extension against force?
