STRETCHY SWEETS EXPERIMENT In this experiment, I am going to find out the relationship between Force and extension using stretchy sweets and then find the stiffness of stretchy sweets using Hookes Law. Hookes Law states that extension in a material is proportional to the force applied provided the proportional limit is not exceeded. To do this, I will use a fixed length of stretchy sweets and suspend different mass of metals on it. Then I will find the extension on the sweet for each suspended metal of known mass. I will carry out first a trial experiment to find out the behaviour of this sweet under different load and to see if it returns to its original length after unloading it. There are several factors that may affect the extension of the stretchy sweet. Some of them are: * The material of the stretchy sweet * The cross sectional area...
