Uniform rod in AP Physics C: Mechanics

Definition

A uniform rod refers to a long, slender object with consistent mass distribution along its length, resulting in equal mass per unit length.

Center of Mass:

The center of mass is the point within an object where its entire mass can be considered concentrated for certain calculations.

Moment of Inertia:

The moment of inertia measures how resistant an object is to changes in its rotational motion and depends on both mass distribution and shape.

Torque:

Torque is the twisting force applied to an object that causes it to rotate around an axis. For example, pushing down on one end of a uniform rod will create torque and cause it to rotate around its center.
