Investigating the factors which affect the time of a pendulums swing

Aim:

In this experiment, we hope to discover which various different factors take affect upon a pendulums oscillation, discover the appropriate formula to calculate the relative factor and how long the pendulum swings for.

Preliminary:

Before we do our main experiment, we need to see which key factors affect the time it takes for a pendulums oscillation. We suspect either one of these three factors: Mss of pendulum, length of pendulum arm and angle of swing.

1)

Middle

Pendulum

11.34

Pendulum + 10

11.19

Pendulum + 20

11.34

Pendulum + 30

11.31

Pendulum + 40

11.37

Conclusion:

Looking at the results, the range is from 11.19 – 11.37. Here is no great difference and is likely to be our mistake as the results don’t descend or ascend in any order at all.

Also mass doesn’t have anything to do with the formula, T=π√l/g.

My prediction is correct.

2) Testing to see whether the angle of the swing is a key point

Prediction:

I predict if we drop the pendulum fairly high, it will

Conclusion

To start off, drop the pendulum at a small angleIncrease angle by intervals of 10 degrees.Record the results each time.

Results

 Angle (degrees) Time (s) 20 11.15 30 11.25 40 11.47 50 11.40 60 11.63 70 11.72

Conclusion

There is a slight increase in time when the angle is bigger; however, there shouldn’t be a change. This may due to length of string being small. If you pull back twice as much, then the gravitational pull also doubles, therefore not affecting the resultant time.

3) Testing length to see if it affects time

Prediction:

I predict that if the length of the string is of a larger length, then it will swing slower

My conclusions also numerically concur with my earlier prediction. This prediction being that if a pendulum had a length of 20cm the time period for ten swings of that pendulum would be 8.96 seconds, this was calculated using the formula for the time period of a pendulum (T = 2?

I will then divide my answer by ten to show the result for the length of one swing. My prediction of the test results I believe that the events which will occur are that the longer the piece of string which holds the weight, the longer the time it takes the pendulum to complete one whole swing.

I also predict that mass will affect the time it takes to complete a period. This is because resultant force is affected by mass. Resultant force is where at least two forces act upon an object along a direction. The overall effect of these forces will decide the motion of

As things like air resistance can effect the time of a period. I think it would be interesting to see if a flat shape would make any difference to the time of the period. I could also change the force of gravity, as there is a smaller force of gravity • Over 160,000 pieces
