Okay...The time period of a pendulum is independant of its mass and amplitude.For the "independance of mass",the reason is that, for same amplitude (distance from mean position), any change in mass would have no effect on the acceleration of the mass (gravitational acceleration is constant);hence the mass will reach the mean position at same time...But for the "independance of amplitude'', the reason I found is that, for a same mass, increase in amplitude would result in increase in restoring force, which would result in increase in acceleration; increased distance would increase acceleration and hence the mass will reach the mean position at the same time...Now my question is that, are'nt these two reasons contradictory, like one says that acceleration remains constant and the other states that the acceleration would increase?Any help will be appreciated...
