... the spring the length of the spring increases, (it stretches) and therefore becomes weaker. The force pulling the spring is pulling on each molecule inside it. The force, acting on the molecules, makes them pull away from each other. When ...

... dimensions or shape) are removed. An elastic material obeys Hooke's law, which states that its deformation is proportional to the applied stress up to a certain point, called the elastic limit, beyond which additional stress will deform it permanently. Elastic ...

... electron needs a certain minimum energy to escape the material but excess energy or surplus energy is transferred to the electron as kinetic energy. Thus creating an electric force, this pushes the electrons around a circuit, known as an electric ...

... as shown in the diagram below. The first thing we did, after setting up the equipment, was to set the spring to its rest point as this was essential for a fair test. We would then pull the spring down a ...
