-- friction in the pivot -- air moving past the pendulum -- the effective length of the pendulum -- the local acceleration of gravity
the swing is produced by the movement of the wind and completely depends upon the movement of the wrists of the bowlers.
Gravity must be overcome.
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.
Potential energy mostly transferring to kinetic energy (some of the energy will also dissipate as heat from friction - air friction, friction where the ends of the chain or rope is rubbing against whatever it is attached to, etc.) The potential energy comes from Jill raising Frank in the gravitational field of the earth.

Every time the pendulum swings back and forth, some energy is lost to friction. Friction with air, and friction in the supporting string or whatever. If you manage to reduce this friction (for example, reduce air friction by making the pendulum swing in a vacuum), it will swing longer. However, you won't be able to reduce energy losses completely; it may swing longer, but not forever.
when it cold and snowing the deer start moving and the rut is in full swing
Force of tension, exerted from the swing rope, keeps the swing moving in the horizontal back and forth motion. The force of gravity keeps the swing from staying at the far right or far left because it always wants the swing to be pulled to Earth, but the force of tension wants to keep it up. Air resistance, like friction, eventually slows the swing down to a halt.
absence of friction...no air resistance
air resistance and friction in the bearings
At the highest point it's potential energy, which is then completely converted to kinetic energy as the swing travels through its lowest point at maximum speed. With an ideal swing (no friction) the sum of potential and kinetic energy stays constant (it is 'conserved'). In practice it dies away as the swing slows down, but Conservation of Energy is an important principle in science.
If you push an object, it starts moving. Good examples (in the sense of not having static friction, which may hinder movement totally if the force is not strong enough) are a person sitting on a swing; or a boat in water.If you push an object, it starts moving.

basically you just swing the wiimote and nunchuck around for a while. and you will notice that mason's hands will start moving alot when you do it.
