Introduction

The Penny Game Coursework! Introduction. Within this investigation we are going to look at variables that affect how far a certain amount of mass travels when sprung across a smooth surface by an elastic band. First of all we will do a trial experiment to see which is the best variable to look at. These variables are; Slope, Pull back, Mass, Type of surface, Space between pins and Thickness of elastic bands. * Slope- to look at the variable slope we tried different gradients but it was to keep it at the same angle all the time. * Pull back- this is a good variable because it gives a wide variety and range of results. * Type of surface- is a very hard variable to look at because you can't range the types of surface in a numerical way so it is hard to analyse my results. * The space between pins with this variable it is hard to do a fair experiment because I would have had to alter the pull back when changing the space because the pins which makes it unfair. ...read more.

Middle

In my trial experiment I have also noticed that it has stuck to my prediction. My real experiment Method > In my experiment I will use; > An elastic band hung between two needles 6cm apart. > I will then place a mass starting with 10g on the board and pull the mass and the elastic band back. > I will then release the elastic band and the mass propelling the mass across the board. > The board will be covered with sugar paper so that it is all the same surface making it a fair test. > Then I will measure how far it travels across the sugar paper. > Then start all over again but increasing the mass each time by 10grams. Apparatus > Elastic band > Two needles > Ten, 10gram masses > A long board about a meter long > Sugar paper > A meter stick Results Mass (g) Pull Back Distance (cm) 1st Distance (cm) 2nd Distance (cm) 3rd Average distance (cm) (to 1dp) ...read more.

Conclusion

> These factors would need to be looked at harder if I ever do the experiment again. The other thing that was odd within my results was how quick my results shot down in experiment 1 compared to the other two experiments. The factors that affected this could be that, > We weren't correctly pulling the mass back enough, > Maybe we were pressing to hard on the mass, > The most likely one is the fact that the person in experiment 1 pulling the mass back was a different person to the person pulling back in 2 and 3 due to he was taken from the class due to personal reasons. In this experiment I could have also made my readings more reliable by doing them to a higher decimal place giving me more accurate readings. I could have done to remove these errors: > Giving each person a job to do with the experiment and making them stick to that assignment. > Another way is to make sure that the surface is flat all over and no bumps. > We could also use a ruler and make sure the mass touches it on pull back so that it is the same distance back every time. ...read more.
