Hooke's Law
The aim of my investigation is to find out if Hooke's Law can be proved with a steal spring and to see what would happen if the spring is stretched beyond the elastic limit.
Planning
In this investigation the following safety rules were applied:
* Long hair was tied back to prevent it from getting in the way.
* People were not cramped together as they needed room to work.
* Goggles were worn to prevent eyes from getting damaged.
* People could not play with equipment.
* People could not run around in the science laboratory.
* Desks were cleared.
There were not to many strict safety precautions used, as the only potential danger was if the spring snapped.
My method of experimentation will be to use a clamp stand and boss clamp to suspend a spring from. A second boss clamp will hold in place a metre rule starting from the bottom of the spring to measure extension in cm. I will then add weights to the spring and measure extension. As I am doing this, I will record my results in a table. I will continue to do the tests until the spring will not return to its original shape. To make the tests fair I will use the same spring and set of weights each time. Also I will add the weight proportionally in 1 Newton (10kg) each time. Therefore the change in weight will remain the same.
My prediction is that Hooke's Law can be proved through a steel spring, as if the weight on the spring will increase so will the extension.
The apparatus needed to do this experiment are a steel spring, a metre ruler, a clamp and weights.
