# To find out what effects the acceleration of a small trolley with a weight of 1kg.

Extracts from this document...

Introduction

What effects acceleration

Aim: To find out what effects the acceleration of a small trolley with a weight of 1kg.

Variables: The variables I will keep the same are:

• the weight of the trolley
• the angle of the surface/slope
• length of the surface/slope
• the surface of the surface/slope

I am going to change the mass acting on the trolley through the pulley. This mass will be measured in grams. I will put on masses from 100g to 800g. I am going to measure the acceleration of the trolley in m/s as the mass on the pulley changes. As the masses will be acted on by gravity they will extent a force on the trolley

Conclusion

Evaluation:

I think my results were fairly reliable all the repeats were consistent. There was one anomalous result, but that was expected. They were reasonably accurate with all values of acceleration to 1d.p or 2 s.f  which was the same as the force. Each test was repeated three times and an average was taken, this improves the accuracy and makes my results far more reliable. I could further my experiment by a change in mass and repeat the experiment. I should get similar results, but the acceleration will always be less e.g

I was also taught that f?=wxsin?, which can be written as ma?=wxsin? as the values are the same and basic substitution has taken place. And since w=mg, this can be added to the equation; thus making it ma?=wxsin?, and we can then change it to mg?=mgxsin?, and as mass is

2. ## Factors affecting the speed of a trolley Travelling down a ramp.

Friction is the result of collisions of the object's leading surface with air molecules. The actual amount of friction encountered by the object is dependent on a variety of factors. The two most common factors, which have a direct effect upon the amount of, friction, these are the speed of the object and the cross- sectional area of the object.
