Investigation to show how Elastic Bands Behave Under Load
Prediction
The aim of the investigation is to determine how elastic bands behave under load. Before I begin the investigation I will carry out a preliminary experiment into the behaviour of a spring, which I believe will not act in the same way as the elastic band.
In the preliminary investigation a spring was put under load and the results were as follows:
Load/g
Length/cm
Extension/cm

From previous knowledge of Hooke's Law, which explains, extension is proportional to load until elastic limit is reached. The preliminary experiment with the spring shows, that they obey Hooke's Law up until the point of
