The bearing on a clock pendulum is usually two knife edges with a cross piece balanced upon it supporting the pendulum. Sometimes on cheaper clocks a very thin strip of springy steel is used.
There are three parts to a pendulum. The bearing, the bob, and the string or wire supportig it.
A pendulum will lose energy in two ways: 1. by friction with the air, 2. by friction in its supporting bearing. Both these energy losses will produce heat.
Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.
A shorter pendulum has a shorter period. A longer pendulum has a longer period.

A pendulum on a knife edge bearing may swing back and forth in a plane (relative to the Earth). A pendulum suspended from aneedle bearingmay swing in elliptical fashion on the surface of a sphere.For the movement to stay parallel to a plane which is fixed relative to the stars, the pendulum must have a needle bearing but no initial momentum perpendicular to that plane. However, the origin of that plane will follow the daily and yearly movements of its location on the Earth. Relative to the Earth, such a pendulum's path will appear to rotate once around every sidereal day (23 hours, 56 minutes, 4 seconds).

A shorter pendulum has a shorter period. A longer pendulum has a longer period.
The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.
bifilar pendulum
maybe it is a pendulum
A heavier pendulum will swing longer due to its greater inertia.
The physical parameters of a simple pendulum include (1) the length of the pendulum, (2) the mass of the pendulum bob, (3) the angular displacement through which the pendulum swings, and (4) the period of the pendulum (the time it takes for the pendulum to swing through one complete oscillation).
The energy of the swinging is converted into heat energy by friction.
Frictionlist pendulum is an example of the pendulum of a clock, a reversible process, free.
