Question

What is si unit of moment of inertia

Answer 1

$\bf\huge\color{red}{ANSWER}$

Moment of inertia may be expressed in units of kilogram meter squared (kg. m2) in SI units and pound-foot-second squared (lbf. ft).

Answer 2

The SI unit of moment of inertia is kg.m²

To properly understand this answer, we have to know more about moment of inertia.

Moment of inertia :

• The moment of inertia can be defined as, "a physical quantity which expresses the tendency of a body to resist the angular acceleration."
• The moment of inertia is a scalar quantity.

Now, this moment of inertia has a SI base unit of kg.m² and this base unit itself is widely used as the SI unit of moment of inertia. (no other equivalent SI unit is there in this case)

Hence, the SI unit of moment of inertia is kg.m²
