Friction in the air. The pendulum actually swings across small air particles and slows it down. That's why, if you have a Bowling ball attached to a string and you hold it up to your face and let go, it will swing back at you - but it is impossible for it to gain enough momentum that you had initially to hit you in the face! Common physics :)

Why is a pendulum not a reliable time standard?
The pendulum is not a reliable time standard mostly because of friction and gravity. To be a reliable time standard, a pendulum would need to form a continuous arc that did not deviate over time. Gravity is always trying to get the pendulum to stop and friction causes the pendulum's fulcrum to resit continued movement. Eventually, a pendulum will stop moving and remain stationary unless acted upon by an external force.
What variables affect the swing of a pendulum?
-- friction in the pivot -- air moving past the pendulum -- the effective length of the pendulum -- the local acceleration of gravity
How can a pendulum be used to produce electricity?
A moving pendulum stores a certain quantity of kinetic energy, whose expression is T = 0.5 L M w^2 where L is the pendulum length M the pendulum mass w the pendulum angular velocity (radiant per second) It is possible to device different methods to transform this energy in electrical energy, for example by charging the pendulum mass and moving it into a solenoid, much like an electrical generator. The result is that the pendulum is slowed more and more up to stop and, while the pendulum speed decreases, electrical energy is created. The total electrical energy E that can be created is E=T-R where R>0 are the unavoidable losses of the system.
Why does a pendulum eventually slow down and stop swinging?
The pendulum will lose energy, due to friction.
When a pendulum wings if it is not constantly pushed it will eventually stop because some of its energy is changed into?
A swinging pendulum will eventually stop because of friction with the air.
What keeps a foucault pendulum moving?
The rotation of the earth keeps a foucault pendulum moving

If pendulum is made to swing in water compare the time taken for this pendulum to come to a complete stop with the time taken by a pendulum swinging in air?
The pendulum will take more time in air to stop completely in comparision with water
How does gravity affect the pendulum to stop?
Gravity doesn't make a pendulum stop. Air resistance and friction in the pivot are the things that rob its energy. If you could eliminate those and leave it all up to gravity, the pendulum would never stop.

The pendulum will lose energy, due to friction.
A swinging pendulum is moving fastest at?
A swinging pendulum is moving fastest at the lowest point of its arc. That is the point where all its potential energy has been converted into kinetic energy, and it is the only point in a pendulum's arc where that happens. See related link (a simulation).
When a pendulum wings if it is not constantly pushed it will eventually stop because some of its energy is changed into?
A swinging pendulum will eventually stop because of friction with the air.
Why did the pendulum keep on moving?
A pendulum will swing nearly endlessly, because it loses very few energy while traveling. Further answer Pendulums don't keep moving forever. They may look as if they are if you only look at them for a minute or two, but they will all slow down and eventually stop if they are not pushed slightly by the clock mechanism neach time they swing.
How can I stop my Grandfather clock from running fast?
You would do it by adjusting the pendulum. By moving it slightly down, you should slow it down. It may take a while to find the correct length.
What factors will cause a pendulum to slow down and eventually stop?
pendulum's slow down during summers because the pendulum expands and it moves faster during winters because the pendulum contracts
