Question

Quizplus · Accepted Answer

The period of a physical pendulum depends on its moment of inertia and the distance from the pivot point to the center of mass, but not directly on its mass, assuming the shape and size are constant and the suspension point is the same for all. Therefore, all three pendulums will have the same period.
