Your work on pearl pendulum has been received. We will look at your data later in the context of the entire group's data on this experiment.
The sounds get closer and closer together. The rhythm also gets faster.
It strikes the bracket less and less frequently. The sounds get further and further apart. The rhythm gets slower.
I placed the bracket on a level surface and the rhythm got faster, so i tilted the bracket forward just a little to make the rhythm steady.
First put one domino under each of the top and left and right corners of a closed textbook. I placed the bracket in the middle of the book with the base parallel to one of the sides of the textbook. The sounds remain overall steady. I rotated the bracket 45 degress counterclockwise and released the pearl, the rhythm also remained steady. I rotated it another 45 degrees and released the pearl, this time the rhythm got a little faster. I rotated it another 45 degrees, and the rhythm also got a little faster. I rotated it two more times to get it back to the origin and one time it got faster then the second time it remained steady.
I would leave the bracket on the book in the origin in which i placed it, it seems to have the most steady rhythm.

The motion between the release and the first hit is the most constant hit, after that they get faster but shorter.
It gets faster, and less constant
it is the fastest hit
N/A
All of the time intervals were about the same.
Because you are releasing the pendulum and still counting the time from the 2nd 4th and 6th hit.
I think that the length of a pedulum does depend on the length of the swing. The swings are longer than if the pendulum was shorter.
