Coursework Investigation

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.

    to help analyse my data and then compare them to my hypothesis. Scatter graph The scatter graph shows two variables in one graph, and allows you to see what kind of correlation they have. There is a positive correlation between height and weight in the data, which supports my hypothesis greatly as I predicted this.

    otherwise it will fall on the floor and possibly cause injury or damage to the apparatus. To stop this from happening, I will face the ramp towards the wall so that the trolley hits the wall at the end of the ramp and it stops moving.

    This can then be manipulated to show the Mach number at which MCRIT will appear, M = 0.7 / Cos 40o = 0.91. This shows that a wing with 40o sweep can reach speeds of up to Mach 0.91 before sonic flow appears.

    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.
