Investigating factors which affect the period of an oscillating spring

Extracts from this document...


Investigating factors which affect the period of an oscillating spring Introduction I have decided to investigate factors, which affect the period of an oscillating spring. Possible factors, which I could investigate, are as follows: * Mass of weight hung on spring * Distance spring is pulled down * Spring used The factor that I have chosen to investigate is the effect of hanging different masses on a spring will have on the period of one complete oscillation of that spring. Prediction I predict that as the mass hung on the spring is increased the period of one complete oscillation will also increase. The formula for kinetic energy is KE=1/2mv2 for all masses hung on the spring the energy within the spring should always remain the same. So according to the formula KE=1/2mv2 As mass increases on the spring there will be a decrease in velocity. Variables Independent variable Dependant variable Control Mass hung on spring The period of one Spring used Complete oscillation Distance spring pulled down The ruler used Safety I will wear safety goggles in case the spring brakes also I will make sure I don't pull the spring down to much with the heavier masses because the spring might become unhooked and weight would fall all over the place. ...read more.


to gain the average time for one complete oscillation. I will also get an average all three results and record all my data in a results table. I will set the stopwatch to zero, load the fist mass on pull the spring down 5cm, start the stopwatch and at the same time release the spring. Stop the stopwatch after 10 complete oscillations and record my results in a table. Repeat this for the other 9 masses and then repeat the whole experiment twice. I will then work out the average for all 3 results and record them in my results table.

My results were very accurate with only a few anomalies. In my graph "period against mass" there is an anomaly marked A this is probably because I pulled the spring to far down so the oscillations occurred quicker due to more energy in the spring. In my graph "t2 against M" there are 2 anomalies marked A and B, possible cause for these maybe the spring was starched beyond its elastic limit with the heavier weights. If I was to improve my experiment I would use more variety of masses although that might cause elastic limit to be reached in the spring I will also consider using a different spring one which can withstand the extra weight. Or I could go up in 50g instead of 100g so I could get a better idea of how much the period of one complete oscillation increases as mass increases. Both of these suggestions give more accurate and reliable results and would give a better average. My experiment supports the conclusion that increased mass increases the period of one complete oscillation of that spring. I would need more time to be able to repeat the experiment and a wider range of masses and larger number of readings. This would give more accurate results. Farid Din 11LO ...read more.
