# Does Centripetal force cause a tangential force?

 P: 37 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: $$F= m\frac{v^2}{r}$$ or using angular velocity, $$F= m r \omega^2$$ But, is there a tangential force acting at the point of mass in its instantaneous direction, and if so, what is it equal to?
