This has caused me to be very confused because at one time i did an experiment, the rubber band followed Hooke's Law, but at another time, it does not.
When I search the internet, some websites state that such experiments are only correctly done when the force is linear with the extension, while some other websites states that rubber bands don't even have a spring constant
I am thinking whether this is due to rubber bands have very low elastic limit?
That's the only explanation I could come up to sort of "fit" the two contradicting theories.
One more question, if the elastic limit does exist, around how big is it? 100N, 200N? I'd like to have an approximate, just a rough approximation will do fine so that i can re-plan a more accurate experiment
