Paul Ruddick Investigating How a Force Affects a Spring In this experiment the factors I will be investigating are the weight applied and the extension of the spring. I predict that the weight inflicted will be proportional to the length of the extension of the spring, until the spring reaches its elastic limit. I have based my prediction on Robert Hooke's Law. Research Elasticity (physics): property of a material that causes it to resume its original size and shape after having been compressed or stretched by an external force. An external force applied to a material creates stress within the material; this stress causes the material to deform. The amount of deformation, as a fraction of the original size, is called strain. For many materials, including metals and minerals, stress is directly proportional to strain over a certain range of these quantities. This relationship is known as Hooke's Law after the British physicist Robert...
