How does extension depend on force??

Question

is there an equation??

Answer 1

Yes. It's called Hook's Law and it goes like this:

F = kx where F is force, x is distance, and k is the 'spring constant'.

You can read all about it in any halfway decent Physics Book ☺

Answer 2

According to Hooke's Law, stress is directly proportional to strain and the constant k is called spring constant...
