my problem is: that the equation is:
A= ae^(-kn)
a is the original amplitude which is 0.1m
n= number of swings.
k= what I/we need to find.
Now when I done the experiment It took 30 swings to get to 0.049m.
But the problem is I have to put this on the graph
so for example after the first swing the value of A= 0.097m.
and it decreased so on, up to the 30th swing to 0.049m.
each swing is 2 seconds long.
Now this is how I plotted the graph, I plotted the graph as decrease in A over time as 30 swings= 60 seconds.
But does that mean the gradient from this line will not give me the value of k?
Because was I suppose to draw a log log graph.
If i was supposed to draw a log log graph how am I meant to do it?
