Introduction

Investigating The Motion of a Mass on a Spring

Planning

I am going to find out how the mass on the end of a spring affects the time period for ten vertical oscillations. I am not going to find out how the mass affects the time period for one oscillation because it wouldn’t be accurate and it will be difficult for me to do the experiment. In result of ten oscillations the result will be more reliable and will be given in accurate conclusion.

My predication for this experiment is that if the mass increase, the time period will increase for ten oscillations. The reason I believe this will happen is because the gravity will pull down the masses and then if the mass is heavy, it will be difficult to go back up. I found all above information from the book (SEG GCSE Double Science Higher Tier) and some leaflets which is handed out to everyone in the class.

I did some research about how mass on the end of the spring will affect the time period, and I found out that

‘ Masses on spring oscillate in a way called Simple Harmonic Motions. The time for one of this oscillation is called time period. The time period depends on various things.

If the diameter and length is different each time I do the experiment, the result will be affect.

Stopwatch

Design

If I use different design, the time may be different and possibly of inaccurate due to PAL / NTSC.

I am going to measure the time in seconds for measuring the mass at ten oscillates. I then will be able to observe the results on the graph and may discover a pattern.

I will use the stopwatch to measure the time in seconds (s)

My Plan

My plan to do this experiment is to find out how the mass on the end of a spring affects the time periods for ten vertical oscillations.

My first step is to collect my apparatus

I am then going to prepare the experiment on the desk and I will make sure it is safely away from other pupils. I then will start the experiment carefully starting from 100g (0.1kg) with the stopwatch and then continue after every hundred grams (0.2, 0.3, 0.4…) to the maximum of 2kg.

I will stop the watch when the mass reached ten oscillate. If needed, I will make the experiment in detail in halves (0.15, 0.25, 0.35.). This will help me to find more reliable results.

Conclusion

I have obtained a couple of odd results. I may get them by letting the spring go by my force or letting the spring go too late or too early. To make odd results accurate, I would need to do the experiment again. As they are not important as my graph produce acceptable line and I guess, I would ignore the odd results.

I think I just got enough results to be certain that my conclusion is accurate because I think I analyse and obtain good results. I have also produce a very good graph. If I need to obtain any more results, I would do an experiment for masse sin 50g e.g. (0.15, 0.25, 0.35…). In the results of that I would be able to produce a better graph as there is more results to analyse from and likely to produce a better conclusions. Above of all, the results are likely to be more accurate and reliable. It will help to improve the rate of this experiment.

    The average was from the two that were completed successfully. We can see from this table and from the graph that was drawn that as the mass on the end of the spring increases the time for the mass to complete one oscillation increases too.

    Discussion: 1. The graph does not pass through the origin owing to the mass of the spring and the movements of its various parts. Besides the mass m, the effective mass of the spring also affects the period of oscillation T. If the effective mass me is neglected, the straight line will pass through the origin.

  1. Determine the value of 'g', where 'g' is the acceleration due to gravity.

    The results are shown below: Number of times the mass of the spring is measured. Mass of the spring (kg) 1 0.046 2 0.048 3 0.046 4 0.046 5 0.048 The average value of the mass is 0.047 kg. This value will be used in the conclusion to find out

    Possible Sources Of Error This is the same as significant sources of error. Most Error Sensitive Measurements According to the calculations that were carried out I came to the conclusion that the most error sensitive measurement is T2. Since we calculate this by squaring T.

    It was apparent, from observation of my younger brother when he was a baby, that he was able to bounce very quickly in his Baby Bouncer. The period of oscillation looked to be shorter than the oscillation period when he was six months older, when he had gained considerable weight (mass).
