Forces, Waves and Radiation Springs Aim To investigate which factors affect the length to which a coiled spring stretches when a force is placed upon it, and whether the size of the coils makes any difference to the results. Prediction I predict that the heavier the weight placed one spring is, the more it will stretch as the greater the mass, the greater the force of gravity is, pulling the spring. I also think that the bigger the coils are, the less amount of weight the spring needs to stretch to its elastic limit. Apparatus * Wire (plastic coated) * Retort stand * 30cm ruler * Pen (to coil wire) * Slotted mass hanger Method To perform this experiment, I am going to take a length of plastic coated wire and wrap it around a pen, which will make the wire into a circular spring. I shall then be suspending the spring from a clamp and stand. I shall then place my...
