Best ResponseYou've already chosen the best response.0dw:1326719932089:dw both string length and pendulum mass and shape and size re same, it is just their starting point different. Will they still swing with same frequency?? What will happen if they start with same height, but different in force initially applied on them, will they still swinbg in same frequency? I am lazy to test them out myself, so ....if anyone of u could give me exact answer, my hypothesis is all of the pendulum with same string length swing with same frequency.

Best ResponseYou've already chosen the best response.3it also does depend on the starting angle of oscillation, because we usually assume the angle is small (less than 10 degrees) so we can make the small angle approximation in the equations of motion \[ \sin \theta \approx \theta \] If \( \theta \) is too large, then this isn't true and the standard solution doesn't hold anymore. You should conduct an experiment (or work the mathematics) to figure out what happens if the starting angle is large.
