Introduction

PHYSICS LAB REPORT

THE EFFECT OF A SUSPENDED MASS ON THE TIME PERIOD OF THE SPRING.

Aim

To investigate the effect of different masses suspended from a spring on the time period of the spring.

Hypothesis

I feel that if I increase the mass, the period will increase too because the mass is proportionate to the time period.

Variables

  • Independent – Mass suspended from spring.
  • Dependent- The time period of the string.
  • Constant- The apparatus, Number of oscillations, spring constant (elasticity).

Apparatus

  • 1 spring
  • 100 gram masses. (6 of them)

Materials

  • 1 clamp stand
  • Stopwatch
  • Plasticine

Method

  1. Place a clamp stand on the table
  2. Attach the spring to the clamp stand.
  3. Add heavy books on the clamp stand to the base so that it is stable and doesn’t affect our readings.
  4. Add Plasticine to the top of the spring so that the spring itself doesn’t vibrate a lot.

Processed Data Table

First as we have three trials I would find the average of the three trials to get one reading for time for 10 oscillations per mass. To find the average I would add the three trials and then divide by three.

Conclusion

I could have used 2 different springs for better results. I could have also noted down the extension in this experiment hence proving Hookes Law as well.There might have been a human error in stopping the stopwatch exactly after 10 oscillations.

Modifications

  • I used Plasticine in my experiment to keep the spring more stable.
  • A also put a heavy weight on the clamp stand so that it does not let anything vibrate which might have altered our results.  

Fair Test

  • I kept the same displacement for each trial.
  • I measured it for the same number of oscillations.

Safe Test

  • We should have handled the mass with more care because the suspended mass was dangerous and kept falling and could break as well.

Response to the question

A topic which is beyond the scope of the GCSE syllabus was experimented by the author. It most definitely answered the question to a certain extent, however lack of further information about oscillations and the relationship between mass and Period (T) is obvious. There is a positive co-relation between the two factors, however it is not directly proportional. This error could have been avoided by simply looking up in internet and learning more about oscillations.

Level of analysis

The analysis is acceptable but limited to only what the student has learnt from the books and not any sort of personal research. There are some mistakes in the essay such as:
1. The apparatus is not a factor so it cannot be considered as a constant factor however the displacement of the mass must be a constant factor.
2. The apparent diagram is not visible in the essay but I blame online file transfers is the blame.
3. The relationship between period and mass hanging from a spring with constant k is T=2? ?(m/k). so T is not just simply directly proportional to m.
But in general it provided some valuable and useful basic information about the topic which is just alright for the GCSE level.

Quality of writing

There were not many writing errors except a few misspelling which usually happens so it is better to use a spelling and grammar checker or proof read your work before submitting it.

    g represents the gravitational acceleration at earth, which remains constant at 9.8 m/s2 . 2? is in the formula because as the tensional force is acting on the string it is moving in a circular motion, but for only a small amplitude, therefore parts of the circumference formula are included in the equation.
