There are several methods that can be used to calculate the density of a metal ball. The density of a metal ball can be derived from the fact that the volume is: 4*(pi)*r^3/3 and the denisty is mass/volume. If the mass and moment of inertia are known but the dimensions of the metal ball are not, then you can use the fact that the moment of inertia of the ball is 2m*r^2/5 and solve for m to get r=(5I/2)^.5 and plug in the value for r into the volume equation then calculate the density of the ball by dividing the mass by the calculated volume.

4 times as great

The ratio is the same. Inertia depends entirely on mass.

A rotating body that spins about an external or internal axis (either fixed or unfixed) increase the moment of inertia.

Inertia is affected by an outside force. So if you calculate the moment of inertia, you calculate the magnitude and possibly the direction of the outside force. You can use this to determine acceleration.

Same as any other material. Glass has a thickness,inertia, area, modulus, etc. like all materials. If u mean strength of glass, ask again

I guess that momentum is part of the inertia, inertia is composed of momentum as the pages are related to the book. Inertia will be different if it has different kind of momentum. Force will affect momentum so inertia will change.

Different velocities is what causes objects to have the same mass and different amounts of inertia. This can be written in a formula.

Inertia is the resistance of any object (in a physical state) to change pressed upon its current movement. It can be found by the Formula F=ma.F being force in relation to inertia, M being Mass, A is Acceleration.

Force and inertia are not the same. They are quite different. They do both have a relationship to the motion of objects having mass.

Inertia can not be destroyed, because inertia is a form of energy and energy can not be created or destroyed it is changed into a different form of energy like light, heat, chemical, or physical energy.

You calculate it using your moment of inertia equations corresponding to the geometry of the object. There's no simple device I don't think that you can buy to just measure it.
