Coursework Investigation

Extracts from this document...

Introduction

Coursework Investigation Planning Aim I want to find out how the height of the ramp affects the acceleration. I think that there are some factors which will affect the investigation which are the height of the ramp and the weight of the trolley. To keep this a fair test I will make sure I keep the same; * Distance travelled * Same trolley * Surface of ramp. I will change one factor of this investigation which will be the height of the ramp Prediction I think that the height of the ramp the faster the acceleration of the trolley. I think this because there is greater force acting on the trolley and less friction on the ramp. ...read more.

this a safe test I will have someone at the end of the ramp ready to catch the trolley as it comes off. During this Investigation, I changed the height of the ramp by these measurements: * 10cm * 15cm * 20cm * 25cm * 30cm Height of ramp Distance Time 1 Time 2 Time 3 Average Speed Average Time Acceleration 10 cm 1m 1.87 2 1.92 4.51 1.93 0.43 15 cm 1m 1.91 1.55 1.57 3.98 1.68 0.42 20 cm 1m 1.31 1.11 1 2.76 1.14 0.47 25 cm 1m 0.95 1 0.98 2.27 0.98 0.43 30 cm 1m 0.82 0.98 0.9 2.1 0.9 0.43 The Graph I will now present my results on a line graph Looking at my results I can easily see that the ...read more.

Conclusion

In my investigation 25cm and 30 cm heights were the slower than 20cm when it should have been faster because of more height should make more force. I think that this may of occurred because of friction, different ramp, didn't stop the stop watch quick enough due to having to use eye sight, height of the table may have also changed the results some how. I could have done this experiment differently which could have made my results much more accurate for example using a ticker timer which would mean we wouldn't have to use our eye sight which is sometimes inaccurate. I could of also used the same ramp all the way threw my experiment so that I would always have the same type of surface. ?? ?? ?? ?? Lewis Francis ...read more.

    By using a scatter graph I should be able to draw a line of best fit, which I can then use to find an equation, which will help me find a result for either the IQ or the Key Stage 2 score if I know what the other result is.

    Nevertheless, these graphs present a weak positive correlation, and when analysing them, I have come up with few conclusions. When comparing these two graphs, I have spotted that the points on the boys' scatter graph are laying much closer to the line of best fit, than those on the girl's scatter graph.

    This is obviously a mistake and therefore I am going to ignore it and choose another child. If I were to include it, I'd have problems. For example, when I do my scatter diagrams, my line of best fit would be inaccurate. Therefore, I have decided to pick another one.

    This would be slightly difficult to investigate because we may be limited by the weights we can use. I will investigate how the height of start position affects the speed of the trolley because it is extremely simple to measure the height and it is also easy to calculate the
