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.
-- its length (from the pivot to the center of mass of the swinging part) -- the local acceleration of gravity in the place where the pendulum is swinging
The acceleration of an object due to gravity does not depend on the mass. Close to Earth's surface, this acceleration is about 9.8 meters per second per second.
No. On Earth the force of gravity or acceleration is always about 9.8m/sec^2 Earth's gravity does not change just because the cart gets heavier lighter.
A pendulum isn't needed to illustrate gravity, and is seldom used for that purpose.It's much easier to illustrate gravity by dropping a book on the floor.But a pendulum is a very useful means of measuring the value of gravity in a place,because the time that a pendulum takes to swing back-and-forth once is very closelyconnected to the local value of gravity. It doesn't depend on the weight of the thinghanging at the end of the string at all ... only on the length of the string and the localvalue of gravity.
The force of gravity on one object due to another object depends on the mass of each object and their separation distance.

That's going to depend on 'relative' to what ?Relative to the acceleration of gravity on Earth, it's precisely 1.000, or 100% .Relative to the acceleration of gravity on Pluto, it's 16.822, or 1,682.2 % .

It does depend on the force of gravity where the pendulum is located. There are other factors that it depends on but their contribution, in normal circumstances, is negligible enough to ignore.
Unless it's in a ship that is accelerating, a simole pendulum will not swing in free space. If it's in a ship that's accelerating, its period will depend on the magnitude of the acceleration.
The length of the pendulum and the gravitational pull.

it depends on acceleration due to gravity as f=mg, when acceleration due to gravity increases the force acting also increases.when force acting increases it cancels the upward thrust(buoyant force)so the body sinks in the liquid.
acceleration due to gravity is given by, g=GM/R2 Hence distance from the earth increases g decreases and viceversa. So g at poles is greater than g at equator.
acceleration due to gravity. it's the same for everything..... 9.8 m/sec
