... bonds, if the bonds break then the molecules cannot return to their original state. This is known as the elastic limit. Therefore, the number of molecules will effect the elastic limit of a material. The more molecules there are the more energy is needed to weaken the bonds. When a load is applied this creates gravitational potential energy(g.p.e). Therefore, materials smaller in width and length need less weight for the elastic limit to be reached. VARIABLES There are several variables which when altered will effect the behaviour of elastic bands and springs. To make a fair procedure their are certain variables that need to be controlled, and others that need to be varied in order conduct the experiment and give a detailed conclusion. The room temperature will effect the experiment, if it drops the particles will vibrate less, and will be drawn closer to each other, meaning the bonds will ...
