Investigation into the effects of a change of angle on the stopping distance of a toy car.

Extracts from this document...

Introduction

Science Coursework: Investigation into the effects of a change of angle on the stopping distance of a toy car. Aim The aim of this experiment is to ascertain how the stopping distance of a toy car is affected by the steepness of the angle of the ramp. Diagram Safety Measures There aren't any safety aspects in this investigation. Apparatus During the experiment I used to the following equipment: Ramp 2x Metre Rulers Matchbox car Boss + Clamp Stand Prediction I predict that the steeper the ramp, the further the car will travel Fair Test To ensure that it was a fair test I made sure that any variables (such as the angle of the ramp for each of the three test runs or change in the surface area) ...read more.

I used the same surface for the test , and I always let go of the car from exactly the same height. This made it so that each of my results would have taken under the same conditions and were accurate. Results The results were as follows: Angle 1st Attempt 2nd Attempt 3rd Attempt Average 30* 41cm 69cm 60cm 56.67cm 40* 93cm 84cm 100cm 92.34cm 50* 124cm 118cm 136cm 126cm Conclusion In this experiment I have found that the steeper the angle then the car will travel faster. This is because gravity can have a greater effect on the car, as the ramp does not get in the way of gravity. ...read more.

Conclusion

I would make the surface the car travelled on much more smooth so the car would not be impeded by anything and making it so the results where a fairer representation of what went on. I would make sure the car was in perfect working condition so that no energy was wasted. Each of my results is similar and that implies that the test was done accurately. If I could do the experiment again, I would do it with the angles and 5* intervals so I could get 6 different readings. This is because it was difficult to get a good picture of the results from a graph. It is difficult to tell if there is any correlation between the results on the graph because there is little to compare them against. Other than that , I have no complaints about this at all. ...read more.

    I collected five sets of results (see results table A) for each mass and then found the average speed. However, when I plotted this on a graph, with a line of best fit, it produced a curve (see chart A), showing that there was no strict rule between the mass and the average speed.

  1. How the height of a ramp affects the speed of a toy car.

    In my results I can see that there is a pattern, the points are mainly on the straight line, which shows that the height and speed are connected, they are proportional to one another. I can see this because as the height increases the speed increases showing that the height is a factor, which affects the movement of an object.

    I also want to find the efficiency of the system. As seen from the comparison between the actual and theoretical results, the efficiency is going to be somewhat lower than 100% (the perfect system). Efficiency in terms of energy transfer can be easily worked out by the following equation: Efficiency
