## Homework Statement

How does a simple pendulum have a constant ω if it's velocity changes?

## Homework Equations

(1) v=ωR

(2) [itex]\omega=\stackrel{\sqrt{l}}{\sqrt{g}}[/itex]

## The Attempt at a Solution

Very confused about this. The pendulum bob is at a fixed distance from where it's attached (i.e R is constant). It seems to me that if the velocity changes, from the equations above, the angular frequency has also got to change. I thought perhaps that the angular frequency derived from SHM was perhaps an average and not instantaneous? But I'm not so sure.
