Okay this is the last question of the lab and I don't get it
Basically its a lab where we find how amplitude, bob mass, and length affects the period T for each time.
Our finding was that length affects the period a lot. I did a bunch of graphs and tables and answered all the questions but don't know how I derive this
the question is "From your graph of T^2 vs. L
determine a value for g."
T here is the period in seconds and L is the length of the string in cm. Now I do have to graph and it looks pretty normal to me.
The slope is 0.03900 and the r is 0.9947
now I don't think this would help much at all
(unless its r-slope haha...)
I have to find g from this graph and calculate the percent of error
I know how to calculate the percent of error but I don't know how I can find g from this graph
the points are for x which is length
50
60
70
80
90
100
and for T^2 i have
2.2831
2.4586
2.89
3.3562
3.7288
My first guess was i need to find an equation for this relationship and then
use the formula 4pi^2/g x L = T^2 but I don't know what to do?
plug in what for L? someone please help!
