Inertia is the tendency of all matter to remain at rest or in motion until acted on by a force. Moment of inertia is a measure of an object's rotary inertia, or its tendency to resist increasing or decreasing rotation about some axis.

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.
❱ 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.
