Physics Investigation 1
Introduction
In this investigation I am going to look at the correlation between the amount and order of springs used and the time it takes for one complete bounce up and down of the spring.
Planning
I started planning this investigation by looking at the safety factors that would be necessary to complete a safe investigation. As this is already a safe investigation there were only two safety points:
) Putting to much weight on the spring so that it hits the desk and springs off.
2) Not keeping the springs on the clamps bar securely so it springs off.
To keep either of these from happening I kept the same weight on the springs at all times which was 400g. Also to keep the second point from occurring I held the springs in place each time I attempted the experiment.
To make this a fair test I kept the weight the same each time I did the experiment also I did each experiment 3 times so that I could work out an average, which would be more accurate than a normal result. I also counted 10 complete bounces of the spring and divided it by 10 so that the time of one bounce would be more precise. I made sure that I started the stop clock as accurately as I could so that my three individual tests would be very similar and this was shown in my results. The variable I am using is the amount of springs used and in what order, this is the only thing I am changing so that my test is fair.
