"Hooke's Law" is about stretching springs and wires. When we apply a force to a spring, it stretches.
If we apply double the force, it stretches twice as much, so long as we don't over-do it.
We measure the original length of the spring when we start. When it stretches, we measure the extension - that's how much longer it is than it was when we started.
Extension = present length original length
Hooke's Law states:- the extension is proportional to the force the spring will go back to its original length when the force is removed so long as we don't exceed the elastic limit.
And no, I'm not the one who submitted this idea....
