By the fact that it stops, also in the vacuum. So its energy was transformed in something also, often heat. Heat is a non mechanical form of energy.

I would say because a pendulum eventually slows down and stops without interaction with something mechanical. The energy that was in the pendulum is lost due to friction with the air or where the pendulum swings from. The energy had not been destroyed. It still exists, it just has changed forms. Since there was nothing mechanical taking the energy from the pendulum, that means that the energy went to non-mechanical events and became non-mechanical energy.

um, both of those answers sucked.
The correct answer is that a pendulum, held away from its center, (where the string is NOT perpendicular to the ground) is full of POTENTIAL energy. When the pendulum is released, the potential energy becomes kenetic energy (energy you can see and feel).

Torquemonkey's answer is best, but it's spelled "kinetic".
