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.

    I have drawn error boxes on my graph so that I can get some idea of what region my answer could lie in. the boxes I have drawn are 2mm*2mm as 2mm is the most accurate I could get my observations due to parallax error.

    This therefore suggests, a lack of any relationship, between boys and girls in KS4. Nevertheless, the scatter graph in my first hypothesis has proved that there is an existence relationship between height and weight of all the KS4 children. I believe that the reason for such a weak correlation I

    Pearson's product moment correlation coefficient varies between -1 to +1. If the value is -1 it is a strong negative correlation and all points lie on the straight line with a slope downwards. If the value is +1 then the correlation is a strong positive correlation and all points lie on the straight line with a slope upwards.
