# Investigation into the Factors Affecting the Speed of a Trolley on a Slope.

Extracts from this document...

Introduction

GCSE Physics Coursework Plan Investigation into the Factors Affecting the Speed of a Trolley on a Slope APPARATUS: * 1kg Trolley * 1kg Masses * Runway * Light Gate * Stop clock * Power Pack * Ruler SAFETY: * Make sure all wires are secured in sockets. * No wires are trailing on slope. * Voltage of light gate has to be between 9V and 15V. * Weights must be put on trolley safely so there is no chance they might fall off. * When putting more than 2 weights on, stack safely. * Turn electricity off after use. * Before use make sure electricity is switched off so not to get a nasty shock. In this investigation I am going to set up a 1kg trolley on a slope and I will be letting it roll. ...read more.

Middle

I will be investigating the speed at 5 different heights ranging from 1cm to 13cm, and on each height I will be varying the mass of the trolley from 1kg up to 5kg.To make it a fair test I will keep the light gate at the same part of the runway each time and start the trolley off at the same point as well. PREDICTION: I predict that the trolley's speed will change due to the varied positions of the runway and the mass of the trolley. The higher the runway is set, I believe the greater the speed of the trolley will be. When we vary the mass of the trolley, I estimate that the speed will increase until the trolley gets a bit too heavy. ...read more.

Conclusion

Although the anomalous results do change the graphs slightly, it is still easy to evaluate from the graphs that the higher the slope is set, the faster the speed is (which is a general rule for physics anyway). The mass of the trolley against the speed didn't make that much of a difference. I think my method is suitable and reliable, on the whole the investigation worked out fine. Sometimes to measure the speed of a trolley we use ticker tape but a light gate, I found, was more accurate and a better piece of scientific equipment. If I had to do the experiment again, the one thing I would change is to get a wider light gate. It was hard to get the trolley to go past it sometimes as the trolley at times seemed to go off its course. Sarah Troy Candidate 2835 Hautlieu School ...read more.

Note: * stands for multiplication Potential Energy By using this formula we can see that as the height of the ramp increases so does the potential energy. This is because the mass, gravitational field and the height are all related and their combined product is the potential energy.

1. ## Physics coursework: Trolley experiment

The movement of an object depends on the relative size of the forces acting on it. To speed up or slow down requires an unbalanced force. More then 300 years ago Isaac Newton carried out an experiments which enabled him to describe how acceleration depends on the size of the unbalanced force and the mass it acts on.
