Pendulum project update

[Darius Clarke]

Andreas,

Scary!
Using your project and unmodified script, I rotated the pendulum so that the 
bob started above horizontal and then started the timer.

The pendulum accelerated! (Great for a perpetual motion machine. You need to 
patent it.)

I know that's the code (limits) and not your challenge.

Does the pendulum accelerate at the same speed and travel distance as a free 
falling object starting at the same height? Or does, assuming a frictionless 
pivot, the limited length of the shaft slow its rate acceleration?

Cheers,
Darius
