what is inertia. Name the factor on which inertia of the body depends
Answers
Answer:
It is needless to state that the inertia of a body depends on various factors. The main factor that affects the inertia of a body is its mass. Mass is surely the main factor that affects inertia.
One can expect the inertia to be more as the mass increases.
This implies that mass has a positive relationship with the inertia of a body.

Answer:-
The moment of inertia, otherwise known as the mass moment of inertia, angular mass or rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis; similar to how mass determines the force needed for a desired acceleration.
Moment of Inertia. The moment of inertia is sometimes called and referred to as "angular mass." It is the "amount of resistance" to rotational motion. ... The moment of inertia is commonly used to calculate torque when multiplied by the angular acceleration.
Moment of inertia about a given axis of rotation resists a change in its rotational motion; it can be regarded as a measure of rotational inertia of the body.
The formula for moment of inertia is the “sum of the product of mass” of each particle with the “square of its distance from the axis of the rotation”. The formula of Moment of Inertia is expressed as I = Σ MiRi²
Moment of inertia of a body depends on the body's mass distribution and the axis of rotation.
The moment of inertia of a body is directly proportional to its mass and increases as the mass is moved further from the axis of rotation.
Hence, moment of inertia of rigid body depends upon Mass & Distance from rotating axis.
