Does the torsional pendulum depend on acceleration due to gravity?
No, a torsional pendulum works with the restoring force provided by the elasticity of the support rod, or (in clocks and watches) by the spring on the balance-wheel.
When were pendulum clocks replaced by more accurate clocks?
In the 1930s
Do some clocks contain mercury?
Clocks that has a pendulum may contain mercury.
What is a pengelom?
That is a misspelling of Pendulum. A pendulum is a weight suspended from a pivot so that it can swing freely. Some clocks have this...
Why was pendulum used in clocks in olden days?
Any mechanical clock or watch (by mechanical I mean non-electric motor driven) uses a pendulum.A pendulum is a great invention; it uses the amount of time that it takes to swing (the period of the swing) to release a single step on a gear (called an escapement gear). No matter how much tension is on the escapement, the pendulum will not swing faster.The time can also be adjusted by shortening or lengthening the distance from the escapement to the pendulum weight.A very cool demonstration is at http://www.howstuffworks.com/gadgets/clocks-watches/clock.htm

Why do all clocks make use of some peiodic motion?
doctor.Galileo Galilee found that a pendulum of a given length takes always the same time to complete one oscillation .this observation led to the development of pendulum clocks .winding clocks & wristwatch's were refinements of the pendulum clocks
