A pendulum
a pendulum
It has a giant spring on it, and when you sit on it the spring pulls back small amounts at the time, causing it to swing back and forth.
A pendulum.
Gravity makes a pendulum swing back and forth. The object starts at one point, and then moves in a circular motion to the apex of it's next point. The kinetic energy becomes less and less as time goes on if no extra energy is added.

A pendulum, which swings back and forth, measures time. It is prominently featured in Edgar Allan Poe's short story "The Pit and the Pendulum," where it is used as a torture device in a dungeon.
Moving back and forth in time is called time travel.
The pendulum of a clock is the long weighted bar that swings back and forth in the case below the clock. It was discovered several hundred years ago that the time it takes for one swing of a particular pendulum is constant, no matter how big or small the swing is. It can, therefore, be used to measure time.

if by arc you mean the "Period" of the pendulum then yes, it does: with each revolution the period of the pendulum (the time taken to swing back and forth once) does decrease.
If you mean the time it takes to swing from start to finish (top to top) this is called the period and if it is the number of swings per second this is know as the frequency.
