Mr
Lim asked this question : "Where is the center of gravity for the pendulum bob? This is where the center of gravity is:
If the pendulum bob was placed on top of the pendulum bob, the center of gravity would be higher because the shape of the pendulum bob has changed .
But if the pendulum bob was spread evenly all over the pendulum bob the center of gravity would still be the same .
