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

  2. 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.

  1. Does the height of a ball affect the diameter of the crater where it ...

    And so I can have an accurate average to put into a graph. The science behind this is, the chemical, which is used in my arm to put the ball at the height it is placed at. The larger the height of the ball the larger the force of G.PE

    These 3 averages would give me a really good insight into what I would predict as a year 7 girls height. The standard deviation shows me the average of the distance in between each piece of data. The standard deviation for year 7 girls was 12.70 cm.

  2. Trolley Investigation

    Therefore h will be directly proportional to v� and a results graph will show a straight line through the origin. According to the equation these would be the values obtained for the v� and this is what the results graph would look like.
