Find the time for 10 swings, repeat this 3 times to get an average for 10 swings. Find the time for 1 swing record the results and calculate time in second. My prediction - as the piece of string gets longer the longer it will take to do a swing. Apparatus - We used a stand G-clamp, string, pendulum, stopwatch and a holder. ...read more.

Conclusion

The answer came to 4.12. My prediction - was that as the length of the string went up the time went up. This was correct and can be proved by looking at the graph. Changing - If I had to change anything to this experiment I would make it easier to measure the length of the string as it is extremely hard to get the exact length. Conclusion - From this experiment I have learnt that the length of the string attached to the pendulum effects the gravity force acting on the pendulum swing. By Ollie Prior ...read more.

This can be shown by the formula for arc length = r? with r representing the length (radius) and ? representing the displacement in radians. If r increases so will the arc length (i.e. distance travelled by bob). This assumption may explain the anomalous nature of the results for the lengths of 1.10m and 1.20m.

Thickness variations are a product of the source and history of the material. Oceanic crust is thinner than continental crust. Continental crust is thickest under mountain ranges. Density variations occur due to the presence of concentrated and large mineral deposits or petroleum gas and related liquids trapped in sedimentary rocks and structures.

I did the same again, but changed the amplitude of displacement to 15�. I wanted to see how much difference there would be, so I could decide whether it was important to devise some sort of system to ensure the same amplitude of displacement each time.

and m = mass (in kg) Normal Force, Fnorm The normal force is the support force exerted upon an object which is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book.

Once the experiment is recorded, transfer it onto a computer or program such as Logger Pro, and analyze your results through graphs, charts etcetera. Make conclusions based on your observations. Observations/Results: While completing this experiment I noticed that the surface of the basketball was relatively rough (implications are further discussed in the in the Discussion section).

Several methods can be used to measure the value of standard gravity. Pendulum This method involves allowing a pendulum to oscillate freely, recording the time taken for each oscillation. The length of the string used to make the pendulum, and the angle of the drop will also have to be measured, in order to calculate the value of g.

* Digital stopwatch * Linear graph paper They were set up in the following way: The pendulum should have swung no further than 10? from the vertical. The experiment was repeated three times to retrieve a more accurate result and twelve readings were recorded over 1.2m. • Over 160,000 pieces
