1 ) Research to look for equations that might help you find g using a pendulum. Design an experiment and test your design and style using Moon and Jupiter. Write your procedure in a paragraph that another student could use to verify the results. Captivate data, graphs, and computations that support your strategy. The time it will take a pendulum to total one back-and-forth swing, known as the pendulum's period, is dependent only for the pendulum's duration and the value of gravity. In an try things out, an experimenter can easily manipulate a pendulum's length. The importance of gravity can not be manipulated.
The ultimate way to find the gravity of any planet/moon using a pendulum should be to use the pendulum to find the period it takes to swing the length of a period. Therefore we know two variables in the equation g=4π2L/(T2), where g is gravity, L is the length of the pendulum, and Big t is the amount of the pendulum. Thus, we can easily find gravity. Do by least twelve trials with varying extent, but usually starting the pendulum at fifteen levels. Record the Length (L) of the pendulum, the time to complete a period (T) in seconds, and T2 (just to make it easier to plug in to the equation later) for each trial.
Either take the average of the gravities found after inserting in T and T2 or you may plot a line of best suit to determine the the law of gravity of a planet/moon and get rid of any outliers.
|Trial |Length of the Pendulum (L) |Time to complete period (T)|T2 |Gravity (g) | |1 |2. 00 m |6. 91 s |47. 7 |1. 66 m/sec2 | |2 |1. forty five m |5. 78 s |33. four |1. 66 m/sec2 | |3 |1. 25 m |5. 46 s |29. 8 |1. 66 m/sec2 | |4 |1. 92 m |6. 77 s...
2 . Make use of your treatment to find g on Planet X. Captivate data, graphs, and computations that support your summary.
3. Give your bottom line and create an error evaluation.
