If the moment of inertia of a body changes due to a change of axis of rotation, the new moment of inertia can be calculated using the parallel axis theorem. This theorem states that the moment of inertia about a new axis parallel to the original axis can be found by adding the mass of the body multiplied by the square of the distance between the two axes.

This is known as parallel axes theorem.

Statement:

If IG be the moment of inertia of a body of mass M about an axis passing through its centre of gravity, then MI (I) of the same body about a parallel axis at a distance 'a' from the previous axis will be given as I = IG + M a2

The proof of the parallel axis theorem involves using the moment of inertia formula and the distance between two axes. By applying the formula and considering the distance between the axes, it can be shown that the moment of inertia of an object about a parallel axis is equal to the sum of the moment of inertia about the object's center of mass and the product of the object's mass and the square of the distance between the two axes.

The perpendicular axis theorem states that the moment of inertia of a planar object about an axis perpendicular to its plane is equal to the sum of the moments of inertia about two perpendicular axes lying in the plane of the object and intersecting the first axis. This theorem can be proven using the parallel axis theorem and considering the individual moments of inertia about each axis. The perpendicular axis theorem is commonly used to find the moment of inertia of thin planar objects.

In physics, the perpendicular axis theorem (or plane figure theorem) can be used to determine the moment of inertia of a rigid object that lies entirely within a plane, about an axis perpendicular to the plane, given the moments of inertia of the object about two perpendicular axes lying within the plane. The axes must all pass through a single point in the plane.

Define perpendicular axes , , and (which meet at origin ) so that the body lies in the plane, and the axis is perpendicular to the plane of the body. Let Ix, Iy and Iz be moments of inertia about axis x, y, z respectively, the perpendicular axis theorem states that[1]

This rule can be applied with the parallel axis theorem and the stretch rule to find moments of inertia for a variety of shapes.

If a planar object (or prism, by the stretch rule) has rotational symmetry such that and are equal, then the perpendicular axes theorem provides the useful relationship:

The moment of inertia of a cube depends on what its axis of rotation is. About an axis perpendicular to one of its sides and through the centre of the cube is (ML2)/6. Where M is the Mass of the Cube and L the length of its side. Due to the symmetry of the cube, you can find the Moment of Inertia about almost any other axis by using Parallel and Perpendicular Axis Theorems.

It's called an ORDINATE.

when there is a straight line 100% parallel to the x axis, it's slope is 0.

If a line is parallel to the y axis, its slope is undefined, or infinite.

To determine the moments of inertia for an object, one can use mathematical formulas or physical experiments. The moment of inertia depends on the shape and mass distribution of the object. Common methods for deriving moments of inertia include integration, parallel-axis theorem, and the perpendicular-axis theorem. These methods involve calculating the distribution of mass around an axis to determine how the object resists rotational motion.

The intermediate axis theorem is important in the study of rotational motion and stability because it explains the behavior of an object rotating around its intermediate axis. This theorem helps predict how objects will rotate and maintain stability, especially in situations where the rotation is not around the principal axes. Understanding this theorem is crucial for analyzing the motion and stability of rotating objects in various scenarios.

Postulates are assumed to be true and we need not prove them. They provide the starting point for the proof of a theorem. A theorem is a proposition that can be deduced from postulates. We make a series of logical arguments using these postulates to prove a theorem. For example, visualize two angles, two parallel lines and a single slanted line through the parallel lines. Angle one, on the top, above the first parallel line is an obtuse angle. Angle two below the second parallel line is acute. These two angles are called Exterior angles. They are proved and is therefore a theorem.

The question doesn't make much sense. I think it probably should say: "an axis parallel to its orbit plane".

In that case, the answer is that Uranus (not Neptune) is the only planet that rotates on an axis parallel (roughly) to its orbit plane.
