(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I have read previous topics about errors, however none have been suited for my problems. Basically, this is for my a level physics coursework, which includes more than this example, but if i crack this then im sure i can do the rest. :)

I am using hookes law (F=kx) to find a spring constant, i have my spring constant but finding the error in it is a challenge.

I have readings which are as follows:

Force (N) Extension (m)

0 0

0.987 0.027

1.962 0.066

2.940 0.104

3.912 0.142

extension error = ±0.0005m

mass balance error = ±0.000005kg

gravity estimation error = ±0.005m/s².

I can find the spring constant from this by drawing a graph and finding the gradient. But what is the error in the spring constant (27.087)?

3. The attempt at a solution

I tried to find the error in each seperate reading, but i couldn't adapt this to find a single error for the spring constant.

Any help with be much appreciated

Thankyou
