Answer:

Moment means moment of inertia.. See.

Explanation:

For smaller objects we suppose them as a particle.But when it is a case of a body of a larger size we cannot make out the body as a particle. We have to calculate the moment of inertia of the object.my pleasure to supply

Here the large object's part are taken as #m_1,m_2,m_3,m_4#.
It is formula that moment of inertia of the mass is #mr^2# when #m# is the mass and the #r# is the distance from the turning axis.
The total moment of inertia of the object is
#m_1r_1^2+m_2r_2^2+m_3r_3^2+...=summr^2#
The moment of the object is written as #I=sumMR^2# or. #intr^2dm#
