Key Stage 3 Science Investigation.
Investigating Hookes Law
Aim: The aim of this investigation is to find out the relationship between the extension and force applied up to the point of distortion.
Theory: Robert Hooke discovered a law for all elastic materials in the seventeenth century. Hooke found that a small force stretched a spring a little and that double the force stretched it twice as much. Hookes Law is that the amount the spring stretches by is proportional to the stretching force. The amount the spring stretches is called extension.
Many materials obey a simple law when compr…
