Introduction


Centripetal Forceimage00.png

Aim: Design an investigation to look at the factors, which affect the velocity of an object moving with circular motion.

Prediction:

I predict that as the radius of the piece of string will get longer the speed of the bung will also increase. There for if the radius is to be shortened the speed will also decrease. I also predict that the as the mass increases in weight at the bottom end of the string the speed will also increase to counter balance.I predict that the force will be proportional to the acceleration and so will also the mass will be proportional to the acceleration. However not in the same way, as the force increases the acceleration will increase but as the mass increases the acceleration will decrease.

Variables:

We can conclude that as the radius of the string increases the speed of the bung also indefinitely increases. This is because it’s got a longer distance to travel in perhaps the same amount of time. From my observations I have noticed that the bung must be exerting some kind of force that lifts the weights. My experiment was a fair one over all except for a few minor occurrences which cannot be helped due to friction.  


Evaluation:

I think that the procedure which I used was the best that I could have done, partly because the results I got were very good. On looking at my results I can tell that they are quite good because the line of best fit goes roughly through the top of all the results.

Conclusion

lessons and then used two different sets of weights, the weights may be slightly more or less and because we did not weigh them on the scales that cud affect the results and so the readings will be different, but as I said it may not affect the graphs too much.

Trying to keep the experiment a fair one was a tricky task. As me and my partner swung the bung over our head it was some times at an angle so the radius would be shorter. As you can see from the diagram below the lower dotted line and arrow are a smaller distance away from the centre which would have affected the results on at least more than one occasion.

    The rate at which an object increases it speed is called the acceleration.
