Pendulum investigation.

Extracts from this document...

Introduction

Pendulum Investigation Information A pendulum will make a repeated swing, which takes a set time. One complete swing is called an oscillation. The time taken for one complete oscillation is called the time period, which is measured in seconds. One complete swing Aim The aim of this investigation is to find out how changing the mass of a pendulum effects the time period of the pendulum. Variables The possible variables for this experiment could be; * Mass of the plasticine. * Height of the pendulum. * The angle at which the pendulum is released. We could keep this experiment a fair test by changing only one variable at any one time. Apparatus * String * Plasticine * Clamp * Stand * Wood * Weighing scales * Ruler *Protractor * Stopwatch Diagrams Method In the test I will use a plasticine ball that weighs 20 grams, I will then increase the mass by 5 grams to get a series of results. ...read more.

* If not attached appropriately the Plasticine could come of the string. To avoid any hazards I will pay very close attention to my surrounding. Prediction I predict that the results will all be very similar, I think this because as the weight increases so does the distance it travels when oscillating meaning the plasticine travels further but it also does this at a higher speed meaning the overall time periods should not vary to much.

Conclusion

Evaluation If I was to do my experiment again when repeating it I would change several things, firstly I would change the variable I tested, I would not have chosen mass I would have chosen the length of the pendulum string the reason behind this is that the outcome of the experiment would be much simpler it would have a clearer and more obvious outcome making my experiment more successful in terms of what I have found out. The second thing I would change would be the amount of oscillations I would test to get the time taken for the pendulum to oscillate, I would time for more oscillations making the overall outcome of each time a more accurate one therefore making my experiment more successful.

    For that work to be done energy must be expended (in the case of a squash/rubber ball, it bounced onto the floor). Some of this energy is dissipated (as heat, etc), but some is stored in the defromed material and is released when the material relaxes.
