5 Swinging Pendulums

For the project I have five pendulums hanging from two
bars. Each pendulum has two strings attached to it. The pendulums swing
downward and collide with each other. When they collide they pass the energy
and the one on the other side begins to swing with the same force as the
original one. I have added some other forces that the user will be able
to change.
The user is able to change the force from gravity. I
know that gravity is about -9.8, but when I used that value the pendulums
swung very fast. Since they moved so fast I decided to reduce the force
from gravity. The user can make it go from 0 to -9.8. The lower the
value the slower the pendulums swing.
The user is also allowed the change the number of pendulums
they want to start swinging with. They have to move the slider to the value
that they want. The user is allowed to choose anywhere from zero to five
pendulums. The user is also allowed to decided how high they want it to
start from. The pendulum is only allowed to go up to 90 degrees.
The wire that the pendulums are hanging from are stiff
wires and can not move or bend. Like I have said before there are two wires
holding each other pendulums up.
The user is also allowed to change the damping force
placed on the pendulums. The damping force is how the pendulum slows down,
and eventually will stop. The user is allowed to change this from zero
to 3. If it is at three it will slow down very fast where if the value
is at zero it won't slow down at all. So a damping force of zero has no
effect on the pendulums.
I was going to have the user be able to change the mass
but in looking into the calculuations of the pendulum swinging I noticed
that the mass of the object ends up canceling out and is therefore not
included in the calculations. Since it would not effect anything I didn't
want to give the user the impression that the slider was going to do anything
so I decided to leave it out.
NOTE:
If you make a change to a slider the program will probably
not take it into account immedialtly. You will most likely have to press
the go button twice to reset the pendulums and take into account the changes
you have made to the different slider values.
My project is kind of like the game where you have 5 pendulums and they
swing. When you pick up two of them and let them go, the two on the
opposite side will also move. I used physics to help me with this.
