How does the weight of a pendulum effect its oscillation time

Plan

The key factors that could affect this experiment are that the length of pendulum varying will change how far it has to swing to complete an oscillation.

The weight of the pendulum will have a effect on the oscillation time because the pendulum will have more weights which will increase the surface area for air resistance to take place this is the only possible way the weight of the pendulum will affect the oscillation time because, gravity is a standard force, so the weight will not effect the amount of gravity taking place.

The angle at which it is dropped at is another key factor because, if it is dropped from higher up it has longer to pick up speed so therefore it shall travel higher up giving it a longer oscillation time. If the pendulum is dropped from a lower then it shall have less time to pick up speed and so will not travel as high up on the other side.

Conclusion

We could have improved our test by having a beam and when it is broke by the pendulum the fifth time the pendulum breaks the beam it could stop timing so it would be the same reaction time for all, we could have had a stand or something to hold the pendulum in place before it is dropped that way we could be sure it was from the same spot each time.

In our experiment there was some slightly out of place results in our experiment but they’re no severe ones that could be anomalous results.

 We could have investigated a further 1000g so we went to 2000g to see if after every 500g there was a jump in time of nearly a second our so, like there was in our experiment. We could also continue to the point of were we have added so much weight that it could not complete 5 oscillations to the same height as it started. We could also have tried the experiment at different temperatures to see what effect, if any it had on the oscillation times.

    It must have been too slow for air resistance to make a significant difference. The results of my angle of release experiments were less conclusive. However it is possible to theorise as to why the results came out this way.

  1. Investigation into the effect of temperature on viscosity

    In the simplest case a comparison between liquids and solids could be made. If we say that a solid has a huge viscosity and a liquid has a medium viscosity, we know from everyday life that to change the state of a liquid to a solid we need to cool the liquid down.

    Conclusion My prediction was proved correct as the graphs clearly show that the speed does indeed increase when the ramp is raised higher. This is due to the fact that more potential energy is given to the trolley as it is raised higher - height is part of the formula

  1. Investigation into the range of a ski jump

    The low power microscope allows the scientist to distinguish to an accuracy of �0.1mm, but the ruler markings are only accurate themselves to �1mm. This means that a compound error is formed and shows why appropriate measuring methods should be used in conjunction with measuring equipment.

  2. Damped Oscillation.

    In my assumption I said that the resistance was proportional to velocity. So. In this case velocity is , hence . My first model of this situation is completed. The model is as follows: * Manipulating the model I am going to solve this differential equation.

  1. The Pendulum

    If you pull on the string or cord that attaches the weight upwards, you automatically give the weight potential energy. It then uses this potential energy in a moment, as the weight falls to drive the clock's mechanism. However the weight of the weight does not effect the period of the pendulum.

    See diagram 1. I will then count one oscillation not when it comes back from when I released it but when it goes through the centre point in the same direction. See diagram 2. I will then carry on counting when it passes through in this direction. See diagram 3.
