I understand how to solve for it and everything...but what exactly IS it? The term "moment" makes me think it has to do with time, but that doesn't make sense. Everwhere I look it just gives me formulas!

The moment of inertia is a physical property of a rigid body that describes its resistance to rotational motion around a specific axis. It is also known as rotational inertia.
The moment of inertia of an object depends on its mass, distribution of mass, and the axis of rotation. The farther the mass is from the axis of rotation, the greater the moment of inertia.
The moment of inertia is calculated by multiplying the mass of an object by the square of its distance from the axis of rotation. It can also be calculated by integrating the mass distribution over the entire object.
The moment of inertia is important in understanding the rotational motion of objects. It is used in various fields such as physics, engineering, and mathematics to calculate the angular acceleration and predict an object's behavior. It also plays a crucial role in designing and analyzing rotating machinery.
Examples of moment of inertia in everyday life include the spinning of a top, the rotation of a bicycle wheel, and the swinging of a pendulum. It is also relevant in sports, such as figure skating and gymnastics, where athletes use their body's moment of inertia to perform certain movements and tricks.
