The pendulum will lose energy, due to friction.
When the pendulum swings up, it gains potential energy, but loses kinetic energy. Therefore when it swing down, it gains kinetic energy, but loses potential energy.
The string that the 'bob' hangs from is a fixed length. So when the bob is off center and over to one side, it must be a little higher than when it's hanging straight down. The restoring force is the force of gravity that pulls it back down to the center.
swinging pendulum has potential energy at each end of it's travel (when it stops momentarily) This energy is converted to kinetic energy as it swings down and back to potential energy as it swings up the other way. Hope this helps you . If the pendulum is long enough it can use the relative motion of the earth's rotation to store just enough energy to maintain a continuous swing.
A pendulum swings back and forth with a period based on its length. When it is pointing directly down, moving horizontally with maximum speed, there is no potential energy; all the energy is kinetic. When it is maximally away from this position it has stopped and so has no kinetic energy; all the energy is potential. Thus at any one time there is the same amount of energy in a swinging pendulum but depending on where it is in its arc of motion there will be different amounts of kinetic and potential energy.

In a pendulum, the energy transformations involve potential energy being converted to kinetic energy as the pendulum swings back and forth. At the highest point of the swing, the pendulum has maximum potential energy, which is then converted to maximum kinetic energy at the lowest point of the swing. This process continues as the pendulum oscillates, with energy being continually converted between potential and kinetic forms.

The 'pend' part of per-pend-icular is derived from the latin 'pendere' which means 'to hang'. Much the same as in words like pendulum, pendant, impending, suspended, all meaning in some form of 'hanging' state. In other words, perpendicular means hanging (straight down at right angles).

A lock of hair hanging down in a spiral curl is known as a ringlet. People who have straight hair can achieve ringlets by using a curling iron.
the earth got its rotation from the axel and the gravity
pendulum's slow down during summers because the pendulum expands and it moves faster during winters because the pendulum contracts
Kinetic energy is the energy possessed by a moving object, calculated as ½mv2. If m is the mass in kg and v the speed in metres/sec the answer will be in joules. Potential energy is sitting there waiting to be turned into kinetic energy. Examples are a mass on a shelf, that will gain kinetic energy if it is dropped off, or energy in a pendulum at the top of its swing when it is stationary. With a pendulum the energy is continually exchanged between potential and kinetic and the total energy (ignoring friction) stays the same (with a real pendulum the total energy runs down because of air resistance).
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.
