The pendulum will lose energy, due to friction.
Air resistance.
Yes. If you take a pendulum and set it swinging it's friction of the pendulum against the air, and internal friction in the line that will eventually slow the pendulum down.
pendulum's slow down during summers because the pendulum expands and it moves faster during winters because the pendulum contracts
To slow down a swinging clock pendulum, one must make it longer. In mechanical clocks, the majority of the mass of the pendulum is contained in the "bob" (a disk or weight) usually at the bottom of the pendulum. If you lower the pendulum bob, the pendulum is lengthened and the pendulum runs slower. This is usually done by turning a nut on a threaded portion of the pendulum just below the bob. Make sure the bob drops as you lower the nut or nothing will change. To raise the rate of the pendulum (make it run faster), you just turn the nut the opposite way.
A slow pendulum clock is sp[eeded up by decreasing the effective length of the pendulum. The weight on the pendulum is usually mounted such that it can be slid up and down the swinging arm. Sliding the weight up slightly decreases the effective length of the pendulum, and slightly increases the rate at which the clock runs. It should be done only in tiny adjustments, because the size of the change might not even be noticeable until a day or two later.

There is a nut on the bottom of the pendulum to adjust the speed. Turning it clockwise speeds it up, counter clockwise slows it down
If the length of a pendulum is increased, the pendulum will take longer to complete a swing, and the clock will slow down. Shortening the pendulum will speed up the clock.
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.
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.
A swinging pendulum follows a simple physical path that is described as simple harmonic motion. A frictionless pendulum would swing forever. Friction generates heat which radiates away energy from the system. Therefore friction will cause the pendulum to slow and stop as all the energy gets removed from the S.H.M. If you rig up a way to replace the lost energy, then the pendulum will continue to swing. This is the method used in a pendulum clock. The energy put into the wind up spring will replace the energy lost due to friction until the spring winds down. The key point is "energy is conserved" which means you cannot create or destroy it. You can only move it from one place to another or convert it into something else.
