what is the period of a simple pendulum 80cm long on the earth and when it is in a freely falling elevator?
imagine a pendulum tilted to some angle.. and dropped frm a building.. what happesn?!
\[T=2\pi \sqrt{L/g}\] when you're on earth (not falling). So if you're free falling, what changes? Nothing. Falling doesn't remove the force of gravity. So the period should not change
Does that help?

are you like obliged to post that all the time? :P
That's not right. Free fall is essentially indistinguishable from weightlessness. The pendulum will not oscillate.
yup.. it will not oscillate!.. it ll just fall :D
