Hooke's Law of elasticity?

Question

i need to know any error that may have occurred because my result show that the extension is not a constant pattern so what may have affected this?

quick need your help this is due moday and i cant think of any!

i would really appreciate it!

The material 'elasticity' gives information about

- Solids

- Limit of elasticity

- Strain

- Stress

- Modulus of elasticity

- Hook’s law

- Elastic after effect

- Elastic fatigue

If you are referring to the stretching of a string,  Hooke's Law states F = -kx.

It is difficult to figure out what you are asking, but if you are asking why x (the stretch of the string, extension?) is not constant, that would mean that F (force) is not constant.  If you pull on the spring, you will apply a force to it.  The force from the spring (Hooke's Law) will balance out your force
