HELP WILL MEDAL. Data and graph included. Calculate the slope of the line in your graph of the square of the period of the pendulum vs. length of the string [slope = (y2-y1)/(x2-x1)]. Galileo figured out the equation that describes the behavior of a pendulum. If you square both sides of the equation, you will find that the slope of the line is related to the acceleration due to gravity (g). Specifically, slope = 4pie^2/g. Use your data to calculate g. How does it compare with the accepted value of 9.807 m/s2?
Calculate the percent error and show your work.

maybe it would be the best if you tried this on your own. it sounds like this is a timed test.

@britanyashton its actually a lab i don't understand i have all the time in the world just asking for help!..but ok thanks.

anonymous · Answer

@britanyashton i even did the graphs and work myself just needed help with the last part don't gotta be rude.

i wasnt trying to be rude actually...sorry if it sounded :(
