is there anyway to calculate inertia in 3d?

for all forms, like we do in 2d, is it the same?

You'll have to be more specific about what you mean by "calculat(ing) inertia in 3d".

the moment of inertia in 3d is it the same for 2d?

It depends.the moment of inertia in 3d is it the same for 2d?

The second moment of area is sometimes referred to as the moment of inertia. This is a property of plane figures.

The mass moment of inertia for 3-D bodies determines how easy or how difficult it is to accelerate a body in rotation.

As I asked before, which of these two properties do you wish to calculate in 3-D?

so there is second moment of inertia and moment of inertia I didn't knew that :/

of course I'm talking about second moment of inertia in 3d, for different shapes...

No, you have confused things.so there is second moment of inertia and moment of inertia I didn't knew that :/
