Inertia is the resistance of any physical object to any change in its state of motion; this includes changes to its speed, direction, or state of rest. It is the tendency of objects to keep moving in a straight line at constant velocity. The principle of inertia is one of the fundamental principles of classical physics that are used to describe the motion of objects and how they are affected by applied forces. Inertia comes from the Latin word, iners, meaning idle, sluggish. Inertia is one of the primary manifestations of mass, which is a quantitative property of physical systems. Isaac Newton defined inertia as his first law in his Philosophiæ Naturalis Principia Mathematica

Moment of inertia➫ A measure of a body's resistance to angular acceleration, equal to the product of the mass of the body & the square of its distance from the axis of rotation.
Examples:-
===========⤵
The moment of inertia of a compound pendulum constructed from a thin disc mounted at the end of a thin rod that oscillates around a pivot at the other end of the rod, begins with the calculation of the moment of inertia of the thin rod and thin disc about their respective centers of mass.
❱ It is also called angular mass.
❱ It is a rotating body's resistance to angular acceleration or deceleration.
❱ It's SI unit is kg m^2.
❱ The mass of a body is roughly a measure of its inertia or resistance to a change in its state of motion.
❱ It is the perpendicular distance from the axis of rotation to a point mass.
