In fact, it is well known that the resonant frequency of the human intestinal tract (approx. 4-8 Hz) should be avoided at all costs when designing high performance aircraft and reusable launch vehicles because sustained exposure can cause serious internal trauma (Leatherwood and Dempsey, ...

This net force causes the bob to slow down.
... Notice how the only time the tension and gravity are equal and opposite is when the bob is straight down. That means there is a NET FORCE in any other position. There are two net forces: 1) Since there is less gravity acting against tension as it rises, there is a net centripetal force (toward the c ...
