GENERAL KNOWLEDGE

Detailed explanation-1: -Indeed, the rotational inertia of an object depends on its mass. It also depends on the distribution of that mass relative to the axis of rotation . When a mass moves further from the axis of rotation it becomes increasingly more difficult to change the rotational velocity of the system.

Detailed explanation-2: -Unless you mean moment of inertia, i.e. rotational motion not linear motion, the distribution of mass does not affect the inertia. The force required to accelerate a mass depends only on the mass and not how the mass is distributed.

Detailed explanation-3: -Thus, inertia is measured in kilograms (kg). In rotational motion, the rotational inertia formula is I=mr2 I = m r 2 or simply I=mr2 I = m r 2, where m is the mass and r is the radius or the distance between the concentration of mass from the axis of rotation.

Detailed explanation-4: -Moment of inertia is defined as the quantity expressed by the body resisting angular acceleration which is the sum of the product of the mass of every particle with its square of a distance from the axis of rotation.

Detailed explanation-5: -The moment of inertia of a body is also known as rotational inertia of a rigid body which is the measure of the amount of torque required to rotate the rigid body around an axis. It depends on the distribution of mass of the body.
