Introduction

Physics Coursework. Natalie Onions Joseph Whitaker School. Plan: This experiment is designed to see if vertical height has anything to do with the speed of a moving vehicle as it rolls down a ramp. We will put a trolley at the top of a ramp and let go. We will start a stopwatch when it reaches the bottom of the ramp and stop it when the trolley has travelled 2 metres. We will experiment with a variety of different heights to obtain better understanding of our results. I think that this is a very easy and efficient way of doing the experiment, as it doesn't require a lot of space or equipment but it will give us results that will be easy to read and spot a pattern in. Diagram: Equipment: Ramp (To roll trolley down) Trolley (Our "Vehicle") Metre stick (To measure our distances and heights correctly) Stopwatch (To obtain correct times for travelling the 2M distance) Scales (Weigh our trolley) Safety: This experiment can be quite dangerous. To prevent accident or injury whilst doing it, we will make sure that we perform the experiment in a clear space, away from other people so that our trolley does not go anywhere near them. Also, if our trolley does move a little too far, we will make sure that we retrieve it immediately to prevent anyone stepping on it and falling. ...read more.

I am going to keep these results as they will make good points to compare my final result to. We will perform each part of the experiment 3 times to get an average result to plot onto a graph. Method: Take the ramp and set it up at the first height chosen. Place the trolley on the top pf the ramp. Mark the floor with some string or the metre ruler at your chosen distance. Let the trolley go, without applying and force to it. Simply let it roll down the ramp itself. Start the stopwatch as soon as the trolley leaves the ramp. Stop the stopwatch as soon as the trolley reaches the set distance. Record your result Repeat with the other chosen heights. Fair Test: To ensure that our experiment goes well and that our results are fair, we will use exactly the same trolley for each part of the experiment. If possible, we will perform our experiment in the same place around the room on each day of the experiment. We will also be as accurate as possible with all measurements and times to get the best results. Our equipment will help with this, as they are very reliable sources. Probably the most important element of fair test in this experiment is the distance we use. Each time, we will make sure that the ramp is the same length and the distance between starting and stopping the stopwatch is also the same. ...read more.

Conclusion

However, if we wanted to improve our timing method, we could have used a Motion Gate. We would have placed one end at the bottom of the ramp so that the clock would be started at the exact moment the trolley went past. The other end would need to be placed at the 2 metre mark so that the clock could be stopped at the exact moment the trolley finished the course. This method of timing would have made excellently accurate results that could be reliable to be correct every time. As said in my conclusion, we found 1 result that stood out. Attempt 3 on our highest height. I don't know exactly why this result was so much smaller than our other results. However, as this was our only result that looked different, we left it in our experiment. We had enough information to draw a conclusion and as our results fit in with our prediction I feel that my conclusion is accurate. If I was to re-write my method, I would have liked to use the motion gates instead of the stopwatch to obtain more accuracy ob my results and I would have also liked to have used a lighter trolley aswell so that we could compare our results and see if mass had anything to do with the result. I am glad that we took our preliminary results when we did as it was this that gave us reasonable heights to begin the experiment with. ...read more.

    Investigating the forces acting on a trolley on a ramp

    5 star(s)

    Friction has a greater effect on the results the smaller the angle becomes, and so because the angles that were worked with were all less than 12�, it is especially noticeable in the results and is be the single most prominent source of systematic error.

  2. Investigating a factor affecting the voltage output of a transformer.

    The problems I found are outlined below, along with possible solutions I might employ in future extension work. * The power supply tripped out too soon after being turned on, with the result that my readings are probably not as accurate as they would have been if I had waited until any fluctuation subsided to take the readings.

    This was done by measuring the distance between points A and E and subtracting the distance between points B and D. The number of books in the stack could then be altered as required. 6. The trolley was allowed to roll down the slope from point A, giving an initial velocity, u, of 0.

    the system makes the machine much more economical to operate, although cooling the system is still extremely expensive, but the key point is that once the electricity has been introduced into the coils then the current will continue at full strength for years without any more electrical input.

  1. To see how the number of coils on an electromagnet affect its strength.

    I will continue to add five more turns on the coils as the experiment progresses. I will plan to do each result to a maximum of five times. A diagram is drawn above of what my experiment will look like.

  2. In this experiment, we investigated the relationship between the difference in work and mechanical ...

    The results will be generated after when we subtract the work of going up the height by the dragging done along the ramp. Our results state that moving an object up an inclined plane than straight up, the amount of effort force required is reduced and accurate distance is required, so the amount of work is the same.

    Laws of Logs The data for the next two experiments will be manipulated(kq) + ln(pmr) Using Law 3, ln(kq) + ln(pmr) = ln(kq) + ln(pmr) This gives the equation lnT = qln(k)+ln(pmr) Comparing this to y=mx+c, the gradient is q, and the y intercept is ln(pmr).

  2. Stopping distance Investigation.

    As before, I will measure the stopping distance, and the time that the trolley takes to pass through the light gate. The third and final experiment that I will do involves altering the starting distances. The starting distance is the distance that the vehicle is placed from the light gate to begin with.
