If I have a string with a lump on the end and is being swung in a circle with a continuous angular velocity then I know that:
[tex] F= m\frac{v^2}{r}[/tex]
or using angular velocity,
[tex] F= m r \omega^2 [/tex]
But, is there a tangential force acting at the point of mass in its instantaneous direction, and if so, what is it equal to?
