Moment of inertia is defined as the resistance against angular acceleration. It is defined as the product of
mass and distance square or we can say square of actual distance. In basic terms it is always defined in
terms of resistance to angular acceleration. Apart from the concept of moment of inertia is highly important in
physics. In understanding various physics concepts, one needs to understand the concept of Moment of
Inertia. This is really critical in some important physics calculation.
Question 1:-
Find the moment of inertia if the mass of the particle is 10 kg and the distance from the reference point is
also 10 m.
Solution 1:-
Given mass of particle, m= 10 kg.
Distance from reference, d = 10 m.
We know that,
Moment of Inertia = m x d2
= 10 * 102 = 1000 Kg-m.
Question 2:-
Find the moment of inertia if the mass of the particle is 5 kg and the distance from the reference point is also
5 m.
Solution 2:-
Given mass of particle, m= 5 kg.
Distance from reference, d = 5 m.
We know that,
Moment of Inertia = m x d2
= 5 * 52 = 125 Kg-m.
