We shall conduct an experiment to determine how the extension
of a spring varies with the stretching force.A spring is hung vertically from a fixed
point and a force is applied in stages by hanging weights from the spring.
The apparatus is set up as shown. For the purposes of this experiment we shall be using
loads of 100g, and the extension of the spring shall be measured in metres.
Each kilogram of mass on Earth has a weight of approximately 9.8 Newtons.
