  This is quite a lengthy question but I'll shorten it so you can digest the gist of the question

  A student sets up an experiment to investigate how the extension of a spring is related to the force applied. So basically, he attached a coiled spring to the retort stand and also a metre rule beside it. He then added on masses from  to 0 to 0.8kg and measure the extension of the spring (with a needle tied to the spring so that it can actually point at the measurement on the metre rule)

  Question: Logically, as more masses are added, greater force is exerted on the spring resulting in a longer extension. Explain this conclusion(why greater force exerted/added onto spring results in greater extension of spring)

  Well, not sure how to explain this but you simply just know that the spring increases in extension. HAHA

   

  Thanks

  Basically, this is Hooke's law.
