Question

Plz explain me about Moment of Inertia

Answer 1

inertia is just a force applied to move any object, for example :
you move a table that can easily move able,
you move a rock which is very hard to move,
next
if you are moving on a bus the sudden break may cause you to move
it is known as inertia

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.
