Inertia and atomic weight are related concepts, but they are not directly proportional to each other.
Inertia refers to an object's resistance to changes in its state of motion. It is a property of matter and depends on the mass of the object. The greater the mass of an object, the greater its inertia, and the more force is required to accelerate or decelerate it.
On the other hand, atomic weight, also known as atomic mass, is a property of atoms and elements. It represents the average mass of the atoms of an element, taking into account the different isotopes and their abundances.
While both inertia and atomic weight involve the concept of mass, they are not directly correlated. Inertia is a property of macroscopic objects and is determined by the total mass of the object, including all its constituent atoms. Atomic weight, on the other hand, is a property of individual atoms and represents the average mass of those atoms.
Inertia can be influenced by factors other than atomic weight, such as the distribution of mass within an object, its shape, and external forces acting on it. Therefore, while atomic weight contributes to the overall mass of an object, it is not the sole determinant of its inertia.
