Primarily they are for time keeping, mechanical clocks and watches all use a type of pendulum.

Pendulums are often used in clocks to power the gears that move the hands. However, most clocks built today often have pendulums only for show, as those types of clocks are usually inaccurate and require a lot of winding.
The period of a simple pendulum, with very short swings, is approximated byT = 2 pi (L/G)(0.5)More complex pendulums, or pendulums with greater than insignificant swing, have more complex equations, usually to correct for circular error.
Inertia is a massive object's resistance to change. It should be obvious then that mass is directly proportional to how long the pendulum swings before coming to rest, since more mass means harder to stop. Mathematically, you'll find this dependence on mass in the damping equations of pendulums.
The time of swing of a pendulum is T = 2π √ (l/g) where l is the length of the pendulum. As T ∝√l (Time is directly proportional to the square root of l) then, the longer the pendulum, the greater is the period. Therefore longer pendulums have longer periods than shorter pendulums.
finding out yes and no answers i think
All pendulums swing. They wouldn't be pendulums if they didn't.
no pendulums are not used for evil or tp provoke evil spirits pendulums are fastinating but are used for questions or any other way you can think of .
The length. Long pendulums are slow, short pendulums are fast.
That one.

You can measure the phase difference between 2 pendulums by measuring the distance between the two. The amount it comes out to will be the difference.
It would also depend on how many pendulums you had, if the regular, 4, the same would happen to the other side.
