Investigation in to Gravitational potential energy.

Extracts from this document...

Introduction

Mohammed Ali

Science Course work Y11 GCSE

Planning

I am going to drop a piece of plasticine imitating a meteorite from certain heights to see whether there is a relation between gravitational potential energy, time, speed/velocity, acceleration, weight with crater depth and crater widths.

I will see whether there is a relation between the factors above by performing a simple experiment.

I will use the following apparatus:

  • Clamp stand
  • 2x 1m rulers
  • bucket
  • sand
  • chunk of plasticine
  • stopwatch
  • myself

I will now annotate how I will construct the apparatus:

Then I will explain my predictions and formulas that I may use during this experiment:

Method

First of all I will measure the weight of the plasticine then I will drop a piece of plasticine from a certain height, record the time it takes to land into the bucket then I will take out the plasticine from the crater it will make and measure the impact depth and impact diameter I will then record results I have found in a table then put them in graph with a best curve of fit.

Conclusion

st graph.

If I had a chance to do it again I could make a more reliable construction of apparatus and maybe other methods could be use.  I could change the height differences e.g. every 10cm instead of 25cm, so I could have more points to plot on the graphs thus giving a more accurate curve.  

Also my investigation could be extended by using an object of another material to imitate a meteorite.  For example, a wooden ball or stone could be used to give results for a meteorite of different density.  Also if I had the facility to investigate the aerodynamics and air resistance of the object would be a plus. And if it is possible work out how much of its mass would burn up in the atmosphere before the impact

My conclusion, I think (‘believe’ would be unscientific) that I gained enough experience in what to do and not do and work on my mistakes so that next time my results wont be so bad and will be of relevant use to me as well as other people.

  1. Bouncing ball investigation.

    It is also directly proportional to x, proving that my prediction was correct, in that changing the independent variable affects the dependent variable; as the height the ball was dropped from increased so did the height bounced. Graph 2 completely undermined my original prediction, this was probably due to the

  1. investigating terminal velocity

    Stop the stopwatch as soon as the cases hit the floor. 5. Record the results in my table. 6. Repeat the height so you have 3 results for each height. 7. Work out the average results. If I follow this method then I should end up with reliable answers.

  2. Trolley Investigation

    As the height increases, so does the angle. So as the angle increases, less energy is lost as friction. Evaluation Our experiment was fairly successful even though our results did not match the prediction. The measurement of the height may have been difficult because we could only measure to the nearest mm.

  1. My investigation is to explore the average student.

    That is why the line carries on for longer than the males' pink line. Also the line for the males' goes up steeper than the females' creating a smaller interquartile range. However, this also means that the median and the upper quartile and lower quartile ranges will be larger than the females.

  2. Mayfield igh Investigation

    Following on from that, I went on to find out the estimated mean. This is probably the most useful average, as it gives you the estimate of what the number is most likely to be. The estimated mean is 154.3 which lie between both the median and modal classes.
