Question

what are the factors on which moment of inertia of a body depends?

Answer 1

I=mk^2

Answer 2

moment of inertia of a body about an axis ONLY depends on how the mass of the body is distributed about that axis

Answer 3

I =\[\sum_{i=1}^{n}\]mi ri^2

Answer 4

mass

Answer 5

you see moment of inertia is rotational analogue of mass

Answer 6

it also depends on the choosing of axes .

Answer 7

\[I=Mk^{2}\] where M= mass and k = radius of gyration.
The moment of inertia plays much the same role in rotational dynamics as mass does in linear dynamics, describing the relationship between angular momentum and angular velocity, torque and angular acceleration, and several other quantities.
