how can the motion of a pendulum illustrate the exchange between potential and kinetic energy. What will happen if a small amount of friction is in the pivot?

You should really do your homework yourself.

1. A pendulum at the height of its swing (aka up) has the max potential energy, which becomes kinetic on the way down.
2. Friction will cause the pendulum to not swing as far.

Btw what grade are you in?

2. Friction gravity i believe will cause the pendulum to not swing as far.

No, because the friction restricts the swinging distance of the pendulum

seems like they got the answer... but still... don't you have a physics book for help?

wouldnt gravity pull the pendulum downward and friction would serve to slow it down to an eventual stop.... but i dunno, im not in physics and i skiped physical science....

I'm not exactly sure i believe you. You consider the collision of one ball hitting the others as friction?

An object in motion will remain in motion unless acted on by an outside force. I.E. Gravity (friction also, but i don't know what you would consider friction)
