I(new)

Definition

In the context of rotational motion, I(new) represents the moment of inertia of an object after a change in its mass distribution or shape.

Analogy

Imagine you have a spinning top. If you add more clay to one side, it becomes harder to spin because the mass is distributed differently. The new moment of inertia (I(new)) takes into account this change in mass distribution.

Related terms

Moment of Inertia (I): Moment of inertia measures an object's resistance to changes in rotational motion. It depends on both mass distribution and shape.

Mass Distribution: Mass distribution refers to how an object's mass is spread out or concentrated. It affects various properties like center of mass and moment of inertia.

Shape: The shape of an object can greatly impact its moment of inertia. Different shapes distribute their masses differently, affecting rotational motion properties.
