inertia is property of mass possesing body to oppose change in linear relative motion

but moment of inertia is the property of a 'rigid' body to oppose rotatory motion along a given axis of rotation passing through the body or outside it.....

moment of intertia is the tendency of a body to resist angular acceleration...

in layman's language... it can be understand as follows..

Linear Motion Circular Motion
Linear Velocity (v) Angular Velocity (ω)
Linear Acceleration (a) Angular Acceleration (α)
Linear Displacement (s)

Angular Displacement (Θ)

Mass (m)

Moment Of Intertia (I)

in other words.. moment of intertia is the anolgue of mass in circular motion...
