kinetic energy
A swinging pendulum will eventually stop because of friction with the air.
It simply loses energy. There is no changing of energy. It is not changed into potential energy, because it has no potential to move anywhere. Potential energy is, for example, bringing a pendulum to close to its apex and typing it there with a string.
The energy changes into is Thermal energy because of the friction caused by it moving produces heat. [Hope it helps]
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 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.

The energy of the swinging is converted into heat energy by friction.
It was 5 when he was with the Rockies and Athletics. It changed to 15 with the Cardinals because Albert Pujols already had number 5 then eventually changed to #7.
If you make the simplifying assumption that everything except the bob is massless, then the mass of the bob has no effect on the period.
nothing would change , may be a slight decrease in the accelration
They have been slowly declining over time because they decay, eventually becoming stable isotopes of other elements.
