... found F I can use this to work out k:
k = F/e
k = 0.4905 / 0.085
k = 5.77 (3sf)
The spring constant in this case is 5.77. Using k I could predict the extension of this spring if the weight suspended ...

What is Hookes Law?
Hokes Law is a rule for a spring,
'For a spring-that for a helical spring or other elastic material the extension is directly proportional to the applied force provided the elastic ...

The effect of applied force on the extension of a spring, using Hooke's Law to predict my results.
