Concept explainers

Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provide resistance in changing its state of velocity or motion for coming to a state of rest. In other words, Newton's first law of motion describes the law of inertia of a rigid body.

Question

If you know a rigid body's moment of inertia about an axis through the center of mass, how do you calculate the moment of inertia for the axis parallel to
the center of mass? (Note: It is not required to prove your answers. Please only describe it. You can directly write the final equation)
