confused!! about period of pendulum hey guys, i have a question. "A meter stick oscillates back and forth about a pivot point at one of its ends. Is the period of a simple pendulum of length 1m greater than, less than or the same as the period of the meter stick?" i thought that the period wouldnt depend on the mass because of what Galileo Galilei found (that the period doesnt change with the amplitude or the mass) so...which i found confusing because the formula does not contain m in it (T = 2 pi root L/g) and the correct answer is "greater than"...i found on some websites that actually the amplitude does change slightly...but what about the mass?? can someone please explain?
