Question

Write the two differences between Mass and Moment of inertia.

Answer 1

It is the resistance to the angular acceleration and is equal to the product of mass of body and the square of its distance from the axis of rotation. Moment of Inertia in a way shows/depicts the mass distribution in a body. For example, ... But Inertia means just the state of the body, whether it is in motion or at rest.

Answer 2

FIRST : "Mass"

Mass is the amount of matter contained in a body >> Measured in Kg (kilogram)

SECOND : moment of inertia.

Moment of intertia is a property of area that's used in mechanics calculations. There's two :

1) mass moment of inertia : equivalent to mass times square the distance to the centre of mass.

I = m * (r^2)

measured in ( Kg.m^2)

2) Area moment of inertia : equivalent to area times square the distance to the centre of shape.

J = A * (r^2)

measured in ( m^4)
