Introduction

SCIENCE COURSEWORK                                                       Anamul Hussain 11A

By: Anamul Hussain

INTRODUCTION:

As for my coursework I will be investigating how a car is going down the slope and the distance of the car and the last acceleration of the car and I will have to measure the distance.

AIM:

My aim for this experiment is to investigate how the speed and distance of a car goes downhill from different heights and angles.

PREDICTION:

My prediction is that the steeper the slope will be the faster the car will go but if the steep is less the car speed will go slower.

SCIENTIFIC THEORY:

The higher the slope is there will be more potential energy the car will have. Because the car

Conclusion

ANALYSES:

The first part of graph 1 is the steepest, it has low steep in the middle but the steep goes up at the end.

The first part of graph 2 is steepest, because the last part has less steep.

In graph 3 the first part is steep and in the middle there is less steep, the steep goes up at the end.

The last graph that is no 4 the first part is steep but in the middle there is less steep. The steep goes up and then down then it goes back to steep at the end.

CONCLUSION:

My aim has been met and my prediction was right.

The graph shows that the car goes faster when the slope is steeper and it goes slower if the slope is less steep and I really liked doing the experiment.

    The surface of the runway and the ramp- the rougher the surface, the greater the contact area between the trolley and the runway, thus more will be the force of friction and thus slower will be the velocity of the trolley when compared to the travel on a smooth surface.
