Introduction

What factors affect the distance travelled by a margarine tub

Aim: My aim is to find out how the distance travelled by a margarine tub is affected by the force applied on it.

Prediction: I predict that the greater the force applied, the further the margarine tub will travel. This will happen because when the elastic band is released, the force exerted by the band will make the forces unbalanced and the resultant force will make the margarine tub accelerate. But however great the force I apply is, the margarine tub will eventually stop. This happens due to air resistance and friction; “friction is a very common force. Whenever one object slides over another (in this case, a margarine tub over a floor)

As you can see, 10N gives an output of over three meters which is too great to repeatedly measure. Also the data is more varied, with a range of 61Cm, compared to 2.2Cm in 5N. If my proper results are this varied, it would be hard to make a clear conclusion. But if they are varied I will compare them with other groups to check that they are accurate.

I will do each experiment five times. After this I will take the mean average, from this I can draw a graph so that I can see my results more clearly. The reason for repeating the experiment is so that the results are accurate and reliable.

I have highlight results which are in consistent.

Even though these specified results seem to be out of place, when looking at the mean average you can see that overall my results are correct. Meaning I do not need to compare with another group.

The graph also shows that as the amount of force being applied (N) is increasing; the resultant force is also increasing.

Conclusion: My prediction was correct as the curve on the graph goes up and my data proves the fact again. The values shown on my graph are the averages, I chose to show the mean average as it was easier to show. But it is also much clearer when looking at and interpreting the data.

    The disulphide bond is one of the strongest bonds known anywhere in nature. The cross-linking by disulphide linkages between the keratin chains accounts for much of the strength of hair. Lighter coloured hair has more of these bonds therefore lighter coloured hair will have a higher tensile strength and elasticity levels.
