# Physics Investigation : Springs

Extracts from this document...

Introduction

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: 1) 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. ...read more.

Middle

Also if they are vertical to each other then the amount of time for 1 complete spring up and down is longer because the springs uncoil more and therefore take longer to recoil. My prediction is also based on the book called 'G.C.S.E Physics' from Wells Library, which has the equation . I timed my results for 10 complete bounces up and down and then divided my results by 10 as I found that it was to hard to measure accurately how long 1 bounce would take. I used the stop clock to time each set of ten bounces. First I pulled down the 400g of mass not to far so that there was no risk of the springs flying of. I then let the spring go up and when it came down for the first time I started the clock and when it came down for the second time I started counting each complete bounce until the 10th bounce came down and when it was at full stretch then I stopped the stop clock. ...read more.

Conclusion

My conclusion supports my theory because in my prediction I stated that there would be a direct positive correlation between the average time it takes for the spring to go up and down and the amount and order of springs used. This is because the more springs there are supporting the mass parallel to each other, then the more compressed energy there is which when the mass is pulled down is released and so is able to move the mass up and down faster than when there are less springs. The more springs there are that are vertical to each other then the longer it takes to reach the bottom because the length of all the springs added up are longer than just one and so it takes more energy for the springs to reach the top so they slow down because they used up to much energy. Also in my prediction I said the equation was correct for this experiment and the above graph shows that half of the equation is right. ...read more.

Dependant variable: Extension (cm) This is the dependant variable which means that this figure relies on the independent variable. Constant: Mass This is the constant which means that this shall stay the same throughout the experiment which was pre-determined by the preliminary experiment.

2. ## Investigation on springs.

* Measuring will take place at eye level so precise and accurate results can be taken. Also this ensures that the reading of the extension is taken at the same place and level to make it a fair test. Also a setsquare will be used to get precise and accurate

Make sure that the bottom of the spring is level with a known measurement on the ruler and make a note of this for use when calculating extensions. Add the first mass and record the extension by taking the total distance the spring has stretched and subtracting the original length

This bounce added to the time taken for each reading to be taken. 3. As the method used required me to estimate the position of the bottom of the spring relative to a ruler located a couple of centimetres away, it was nessicary that my eye level was the same

1. ## Investigation on how putting springs in series and parallel affects their extension.

As I had predicted earlier, the spring constant of the single spring (2.30 x10-2) ??2x the spring constant of the two springs in series (1.14 x10-2). However the spring constant of the single spring is not quite half of the spring constant of the springs in parallel, yet it may

In a standing wave, produced by the closed air column, the same number of cycles are covered per second except the incident wave starts as a crest and the reflected wave begins as a trough. This represents identical frequencies just like the pushing frequency matches the frequency of the swing.
