Question

Which has more inertia: a bowling ball or a golf ball.

Answer 1

The sum of the product of the mass of each particle with its square of the distance from the axis of rotation is the moment of inertia, which is the amount indicated by the body resisting angular acceleration. Or, to put it another way, it's a number that determines the amount of torque required for a certain angular acceleration in a rotating axis. The angular mass or rotational inertia is another name for the moment of inertia. $kgm{s^{ - 2}}$is the SI unit for moment of inertia.

Complete answer:
The resistance of any physical object to any change in velocity is known as inertia. Changes in the object's speed or direction of motion are included. The tendency of things to continue travelling in a straight path at a steady speed when no forces operate on them is one example of this characteristic. The notion of inertia is a fundamental concept in classical physics that is still used to describe how things move and are influenced by applied forces. Unless disturbed, a body travelling on a level surface will continue in the same direction at a steady pace.
Mass is measured by inertia. To accelerate at the same pace, an item with less inertia will require a little force. An item having a higher inertia, on the other hand, takes more effort to accelerate at the same pace. The inertia of a bowling ball is greater than that of a golf ball because the bowling ball has more mass.

Note:
Depending on the context, the term "inertia" can refer to an object's "amount of resistance to change in velocity" or, in simpler terms, "resistance to a change in motion" (which is measured by its mass), or it can also refer to its momentum. The term "inertia" is better understood as a shorthand for Newton's "principle of inertia," which states that an item that is not subject to any net external force travels at a constant velocity. As a result, an item will continue to move at its present velocity unless a force causes it to change speed or direction.
