Mere and Ruth investigated the relationship between the applied force, F, and the extension, x of a spring. The results they obtained are shown in the table below.
Force F (N) Extension x (M)
0.0 0.0
2.0 0.033
4.0 0.066
6.0 0.099
8.0 0.132
10.0 0.165
state the type of relationship between force and extension.
calulate the gradient of the graph line. Show your working and give a unit with your answer.
State the equation of the relationship between F and x.
The spring constant is the force required per metre of extension of the spring (k = f/x)
Use this formula and your equation to find the value of the spring constant of the spring. Show your working and give a unit with your answer.
