The bob pf a pendulum (like a grandfather clock) swings through a circular arc of constant radius. At what point of the swing does the cord holding the bob exert the greatest centripetal force on it?
How do you figure this out?|||at the very bottom its swing. think of when you ride a roller coaster. you feel yourself get heavy when you go fast and close to the ground (at the very bottom. where have you heard this before?)
