4.2: Newton's First Law of Motion
Mass. The property of a body to remain at rest or to remain in motion with constant velocity is called inertia. Newton's first law is often called the law of inertia. As we know from experience, some objects have more inertia than others. It is obviously more difficult to change the motion of a large boulder than that of a basketball, for ...

What Is Moment of Inertia in Physics?
The moment of inertia of an object is a calculated measure for a rigid body that is undergoing rotational motion around a fixed axis: that is to say, it measures how difficult it would be to change an object's current rotational speed. That measurement is calculated based upon the distribution of mass within the object and the position of the …

Moment of Inertia
Moment of Inertia Examples. Moment of inertia is defined with respect to a specific rotation axis. The moment of inertia of a point mass with respect to an axis is defined as the product of the mass times the distance from the axis squared. The moment of inertia of any extended object is built up from that basic definition.

7.7: Calculating Moments of Inertia
Moment of Inertia. We defined the moment of inertia I of an object to be [I = sum_{i} m_i r_i^2 ] for all the point masses that make up the object. Because (r) is the distance to the axis of rotation from each piece of mass that makes up the object, the moment of inertia for any object depends on the chosen axis.

Moment of inertia for a hollow ball calculation
In summary: This is why it is important to only give the mass of the solid sphere in your problem, and not the radius, a, or the density, ρ. If you want to calculate the moment of inertia of a hollow sphere, you would need to calculate the mass of the solid sphere before it is hollowed out, and then use that value in place of the (31/80)ma2 for …

Moment of Inertia | Brilliant Math & Science Wiki
The moment of inertia is a physical quantity which describes how easily a body can be rotated about a given axis. It is a rotational analogue of mass, which describes an object's resistance to translational motion. Inertia is the property of matter which resists change in its state of motion. Inertia is a measure of the force that keeps a …
